Luo, Liping;Xu, Longhua;Meng, Jinping;Lu, Jiahui;Wu, Houqin published 《New insights into the mixed anionic/cationic collector adsorption on ilmenite and titanaugite: An in situ ATR-FTIR/2D-COS study》 in 2021. The article was appeared in 《Minerals Engineering》. They have made some progress in their research.HPLC of Formula: 89-73-6 The article mentions the following:
Elucidation of the co-adsorption characteristics of multiple functional groups will help to screen suitable reagents to improve the floatability and comprehensive utilization of valuable minerals. Herein, salicylhydroxamic acid (SHA), an anionic collector with two functional groups, mixed with a cationic collector dodecylamine (DDA) in ilmenite-titanaugite flotation system was in-depth studied mainly using in-situ attenuated total reflectance Fourier transform IR spectroscopy (ATR-FTIR) combined with the two-dimensional correlation spectroscopic anal. (2D-COS) and XPS. The highest flotation separation performance, at pH 8-9, can be achieved using the SHA/DDA complex with a molar ratio of 6:1. Moreover, at. force microscope (AFM) anal. ulteriorly proved the selectivity of the mixed SHA/DDA collector in the ilmenite-titanaugite flotation system. In-situ ATR-FTIR combined with 2D-COS gave the characteristic sequential adsorption and interaction with the functional groups related to SHA/DDA, which was further confirmed in the results of XPS. The preferred adsorption configuration for the adsorption of the mixed collector were drew to explain the flotation separation between ilmenite and titanaugite. It is predictable that the detailed study into the hybrid collectors with multiple functional groups will provide new insights into the design, synthesis and development of more-powerful collectors. And N,2-Dihydroxybenzamide (cas: 89-73-6) was used in the research process.
N,2-Dihydroxybenzamide(cas: 89-73-6) has also been shown to be active against wild-type strains of Candida glabrata, but not against resistant mutants. HPLC of Formula: 89-73-6 This drug may have therapeutic potential for bone cancer and metabolic disorders such as obesity.
