Abstract

In this study, we have proposed a novel decomposition agent composed of Cu(II) and soluble chitosan for organophosphorus chemical agents. Compared to the autohydrolysis, the soluble Cu(II)-Chitosan complex hydrolyzed DFP more effectively. Results show that soluble Cu(II)-Chitosan complex enhances the hydrolysis of DFP in 4~6 folds compared to the autohydrolysis of DFP in buffer solution. This study provides the possibility of using this soluble Cu(II)-Chitosan complex as the environmental friendly decomposition agent which can substitute current DS-2 decomposition agent.
