Preferring cellulose of Eichhornia crassipes to prepare xanthogenate to other plant materials and its adsorption properties on copper.

Choosing bio-material of Eichhornia crassipes from five plant materials through comparison on their exchangeable capacity to copper and carboxyl content, cellulose xanthogenate was prepared by raw fiber of E. crassipes with NaOH and CS(2). The exchange adsorption properties of the product on copper were investigated and the optimum preparing condition was obtained.
