Removal of toxic heavy metals, phenolic compounds and textile dyes from industrial waste water using phosphonium based ionic liquids

This article focused on a comprehensive result of the development of three phosphonium based room temperature ionic liquids (RTILs) of same cation, trihexyltetradecylphosphonium ([PC6C6C6C14]), with different organic or inorganic anions viz. [Cl-] chloride dicyanamide [-N(CN)(2)(-)] and bis (trifluoromethyl sulfonyl) amide [-NTf2-] in extraction processes of toxic textile dyes as rhodamine B, methylene blue, methyl orange, malachite green, alizarin red S and congo red dyes from their aqueous solution, harmful heavy metals include As, Cr, Cd, Cu, Zn, Pb and Hg from their standard solutions AS(NO3)(3), Cr(NO3)(3), Cd(NO3)(2), Hg(NO3)(2), Pb(NO3)(2), Zn(NO3)(2) & Cu (NO3)(2) respectively and phenolic compounds from rice and cashew industrial waste water. In technological front, ILs revealed a potential ability for the removal of dyes, heavy metals and phenolic compounds owing to their hydrophobic nature on investigating via liquid -liquid extraction method. The effect of contact time, solution pH and initial concentration of dyes were investigated and the result show that adsorption of dyes increases with increasing contact time and gets maximum decolourisation at acidic pH and pH 7. The extraction process of heavy metals with the ILs were investigated and were assessed using the techniques UV-Visible spectroscopy and ICP-MS (Inductive Coupled Plasma Mass Spectroscopy). The three ILs showed best extraction efficiency (approx. 100%) for all heavy metals and the dyes using proposed methodology. UV-Visible Spectroscopy quantification method was employed to analyse extracted phenolic compounds. Screening results of phenolic compounds have shown that [PC6C6C6C14][Cl] IL exhibited the capacity intake of 100% efficiency from rice and cashew industrial waste water. The Its were characterized with thermogravimetry (TGA) and from which, the samples showed a good thermal stability up to 573 K to project them as promising one for high temperature needs in various technological fronts. Toxicity risks of the three ILs and the textile dyes used were examined by in silico OSIRIS software calculations and the ILs were found to be non-toxic. (C) 2020 Elsevier B.V. All rights reserved.

Estimation of the late postmortem interval using FTIR spectroscopy and chemometrics in human skeletal remains

Due to a lack of reliable and accurate methods, determining the postmortem interval (PMI) of human skeletal remains is one of the most important and challenging tasks in forensic medicine. In this paper, we studied the changes to bone chemistry with increasing PMI in two different experimental conditions using Fourier transform infrared (FTIR) spectroscopy in conjunction with chemometrics methods Paired bone samples collected from 56 human corpses were buried (placed in soil) and unburied (exposed to the air) for intervals between 76 and 552 days. The results of principle component analysis (PCA) showed the chemical differences of these two cases had a significant influence on the rate of decomposition of the remains. Meanwhile, satisfactory predictions were performed by the genetic algorithm combined with partial least-squares (GA-PLS) with the root mean square errors of prediction (RMSEP) of 50.93 days for buried bones and 71.03 days for unburied bones. Moreover, the amide I region of proteins and the area around 1390 cm (1), which is associated with fatty acids, were identified with regular changes by GA-PLS and played an important role in estimating PMI. This study illustrates the feasibility of utilizing FTIR spectroscopy and chemometrics as an attractive alternative for estimating PMI of human remains and the great potential of these techniques in real forensic cases with natural conditions.

Nano-dispersion of organo-modified nanofiller in partially fluorinated matrix as the polymer/magnetic nanoparticle composites

A transparent and flexible crystalline polymer nanohybrid was fabricated, containing well-dispersed magnetic nanoparticles (MNPs) with organic chain-modified surfaces. The partially fluorinated copolymer matrix used is composed of switchboard-type lamellae. These become transparent owing to the creation of high-density amorphous regions on drawing the corresponding film at just below the polymer melting point. Although the creation of oleo- and hydrophobic fluorinated polymer/organo-modified MNP nanohybrids is generally difficult, formation via melt compounding was confirmed using wide-angle X-ray diffraction and thermal analysis. On organo-modification of the hydroxyl-terminated MNP surface with long-chain fatty acids, the resulting improvement in wettability aids the dispersion of the particles and hence maintains transparency. Nano-dispersion of the organo-filler was considered to result from surface modification-induced improvement of particle miscibility and melt compounding. These nanohybrids have enhanced thermal degradation temperatures and mechanical properties, derived from the nucleation effect caused by the adsorption of the terminal polymer chains onto the organic modifier.

Ag1Pd1 Nanoparticles-Reduced Graphene Oxide as a Highly Efficient and Recyclable Catalyst for Direct Aryl C-H Olefination

The efficient and selective palladium-catalyzed activation of C-H bonds is of great importance for the construction of diverse bioactive molecules. Despite significant progress, the inability to recycle palladium catalysts and the need for additives impedes the practical applications of these reactions. Ag1Pd1 nanoparticles-reduced graphene oxide (Ag1Pd1-rGO) was used as highly efficient and recyclable catalyst for the chelation-assisted ortho C-H bond olefination of amides with acrylates in good yields with a broad substrate scope. The catalyst can be recovered and reused at least 5 times without losing activity. A synergistic effect between the Ag and Pd atoms on the catalytic activity was found, and a plausible mechanism for the AgPd-rGO catalyzed C-H olefination is proposed. These findings suggest that the search for such Pd-based bimetallic alloy nanoparticles is a new method towards the development of superior recyclable catalysts for direct aryl C-H functionalization under mild conditions.

Synthesis of Vicinal Bromoamine Compounds via Three Components Reaction of beta,beta-Dicyanostyrene/Amide/N-Bromo-succinimide

Vicinal bromoamine derivative belongs to an important class of difunctionalization compounds. New synthetic method and new vicinal bromoamine derivatives are eagerly desired. Thus, a new one-pot protocol for the synthesis of vicinal bromoamines from beta, beta-dicyanostyrene derivatives/amides/N-bromo-succinimide was developed. In the presence of anhydrous K2CO3, beta, beta-dicyanostyrenes reacted smoothly with amides and N-bromo-succinimide (NBS) to generate the vicinal bromoamine compounds in good to excellent yield (up to 93% yield) at room temperature without the protection of inert gas in CH2Cl2. 13 different structural beta, beta-dicyanostyrene derivatives reacted with 7 different structural amides (acrylamide, acetamide, valeramide, isobutyramide, benzamide, 4-nitrobenzamide, ethylurethanm) and NBS have been investigated in this work. The results indicated that the method is not only widely subjected to beta, beta-dicyanostyrene, but also suitable for the different type of amide. The structures of all the products were confirmed by their nuclear magnetic resonance spectroscopy (NMR), infrared spectra (IR) and high resolution mass spectrometry (HRMS), and the possible reaction mechanism was proposed.

2-Bromo-5-hydroxy-6-nitropyridine (132.8 g, 0.606 mol), cesium carbonate (594.7 g,1.83 mol), tert-butyl methylcarbamate (116.7 g, 0.890 mol) and anhydrous DMF (4.0 L) were combined and the resultant orange mixture was sparged with nitrogen for 10 minutes. Xantphos (53.1 g, 0.0918 mol) and palladium acetate (13.5 g, 0.0601 mol) were then added and the solution was heated to 80C with continuous nitrogen gas sparging for 3 days. The mixture was allowed to cool and stir overnight. 2-Methyltetrahydrofuran (MeTHF, 4.OL) wasadded and the resultant slurry was stirred for 2.5 hours and then filtered through Celite. Thefilter cake was washed with 2 x 1.0 L of MeTHF. The filtrate was then partitioned with 8.0 Lof water. The organic layer was discarded and the aqueous layer acidified to pH 1-2 with 60mL of 12N HC1. Ethyl acetate (4.0 L) was added and the layers were separated. The organic layer was washed with water (2.0 L). The aqueous layer was back extracted with EtOAc (2 x2.0 L). The combined organic extracts were concentrated on a rotary evaporator to a brown oil. The residue was twice dissolved in EtOAc (1.0 L each time) and concentrated again. The brown oil was then dissolved in MTBE (300 mL) and loaded onto a silica gel column (SiliaFlash G-60, 3.0 L, 1.5 kg) that was pre-conditioned with 10% EtOAc/n-heptane. Thecolumn was then eluted sequentially with 10%, 20% and 30% EtOAc in n-heptane. The fractions were discarded until the eluate was yellow and then collected until cessation of color. Concentration of the combined yellow fractions on a rotary evaporator yields two crops of tert-butyl [5-hydroxy-6-nitro-2-pyridinylj(methyl)carbamate of 61.5 g and 21.3 g, (respective LC purities = 98.7% and 97.0%) with a combined yield of 82.8g (51%).

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
