双室隔膜电解池降解壳聚糖研究
Degradation of chitosan by a double-chamber diaphragm electrolysis cell
摘要
Abstract
An economical and rapid degradation of chitosan can be achieved by using electrochemical anodic oxidation reactions to generate reactive oxygen species that can attack chitosan glycosidic bonds.However,at high density currents,a localised alkaline environment unfavourable to chitosan degradation is formed at the cathode.This alkaline environment produces adsorption and gelation of chitosan in solution,thus reducing the anodic degradation rate.Based on the regulation of the cathode of the degradation counteraction,this study was carried out to prepare chitosan and hydrogen by constructing an electrochemical dual-compartment diaphragm degradation to decompose chitosan(anode)and water(cathode),respectively.It was shown that chitosan could be rapidly degraded at high current by using dual-compartment diaphragm degradation,and 94%degradation rate could be achieved in 60 min at 160 mA/cm2 current.Notably,the cathode did not precipitate colloids and produced hydrogen.关键词
