Water wettability of Si/SiO2 surfaces was controlled by the formation of SAMs terminating in 1-alkyl3-(3-silylpropyl)imidazolium ions and the anion exchange on the surfaces (“direct anion exchange”). The exchange was confirmed by X-ray photoelectron spectroscopy, and the water wettability was measured as a water contact angle by contact angle goniometry. We found that anions played a great role...
A synthesis method of new fibrous anion exchangers with strong base groups has been developed. The was carried out by alkylation weakly basic based on polyacrylonitrile fiber using two alkylating agents: epichlorohydrin and ethylene chlorohydrin. influence the reaction conditions physicochemical properties investigated. parameters were determined: molar ratio “amino groups: agent”, concentratio...
Copper chloropyrophosphate frameworks have been synthesised with a wide variety of complex inorganic anions trapped in a large, flexible, one-dimensional pore, with anions including chloride, bromide, phosphate and the complex metal halo-anions PtCl(4)(2-), PdBr(4)(2-), CuCl(4)(2-) and AuCl(4)(-).
Acetic acid is a compound commonly found in hemicellulosic hydrolysates. This weak acid strongly influences the bioconversion of sugar containing hydrolysates. Previous investigators have used anion exchange resins for acetic acid removal from different hemicellulosic hydrolysates. In this study, the efficiency of an anion exchange membrane was compared to that of an anion exchange resin, for a...
