Li, Hugang;Cao, Maojiong;Zhang, Yuanhui;Liu, Zhidan published 《Hydrothermal liquefaction accelerates the toxicity and solubility of arsenic in biowaste》 in 2021. The article was appeared in 《Journal of Hazardous Materials》. They have made some progress in their research.HPLC of Formula: 112-84-5 The article mentions the following:
Arsenic (As) is one of notorious metalloids due to its high toxicity to human beings and ecol. system. Understanding its fate and speciation transformation mechanism during hydrothermal liquefaction (HTL) of microalgae is of crucial importance for the application of its HTL products. 80.0-96.7% of As in raw microalgae was migrated into the liquid phase (aqueous phase and biocrude oil) with the increase of reaction severity from 0.108 to 0.517. HPLC-ICPMS reveals that 67% of the As in microalgae accounted for As(V) with a concentration of 68.4 mg/kg. The other fractions in microalgae were primarily As(III) with a concentration of 36.3 mg/kg. Model compounds experiments illustrate that over 30% of the As(V) in feedstocks was unexpectedly converted into more soluble and toxic As (III). Hydrochar containing O-containing groups (e.g., aliphatic C-OH) was probably contribute to the reduction transformation of As(V) to higher toxic As(III). Meantime, the aqueous phase facilitated the reduction reaction via providing a reducing environment and serving as hydrogen donator. This study firstly revealed the speciation transformation of As(V) to As(III) during HTL of wastewater cultivated microalgae. To complete the study, the researchers used cis-13-Docosenamide (cas: 112-84-5) .
cis-13-Docosenoamide(cas: 112-84-5) is a primary fatty amide resulting from the formal condensation of the carboxy group of erucic acid with ammonia.HPLC of Formula: 112-84-5 It is commonly used as a slip additive in the plastic manufacturing industry.
