Chromium retention properties of N-alkyl quaternized poly(4-vinylpyridine)
(2009)
The ability of solid N-alkyl quaternized poly(4-vinylpyridine) with hexyl, octyl and decyl bromide for the retention of chromate and dichromate forms of Cr(VI) in aqueous solutions is studied. The retention of Cr(VI) was ...
Synthesis and characterization of poly (ionic liquid) derivatives of N-alkyl quaternized poly(4-vinylpyridine)
(Elsevier B.V., 2018)
© 2018 Elsevier B.V. The main motivation of this work is to obtain poly (ionic liquids) (PILs) derived from poly (4-vinyl pyridine) of different hydrophobic character containing BF4 −, PF6 −, (CF3SO2)2 N− and CF3SO3 − as ...
Trimethylchitosan hydrochloride obtained from lobster carapace chitin on a bench scale
(Biointerface Research Applied Chemistry, 2019-10-15)
Starting from the chitin obtained from the lobster carapace, chitosan was obtained. This polymer, due to its high biodegradability, biocompatibility and mucoadhesivity, has a wide use in the pharmaceutical and food industry. ...
Determination of the degree of substitution of modified chitosan by cyclic voltammetry at water/dichloroethane interface
(Elsevier, 2014-12)
The electrochemical behavior of the cationic polymer chitosan-gtmac (Ch-GTMAC), at the polarized water / 1,2-dichloroethane interface was studied. This polymer was obtained by nucleophilic reaction of chitosan (Ch) with ...
