Abstract

A novel sulfur ion exchange fiber - thiosemicarbazide chelating ion exchange fiber (TSCIEF) was prepared by nucleophilic substitution reaction of chloramethylated polypropylene graft styrene (CPP-g-St) fiber and thiosemicarbazide, using anhydrous ethanol as swelling agent. The structure of TSCIEF was characterized through IR, TG, DTG and SEM testing. The adsorption capacity of TSCIEF on Au ( ) were evaluated. The results showed that the adsorption capacity of TSCIEF on Au ( ) was 142 mg•g-1. What’s more, the TSCIEF has an excellent selective adsorption on Au ( ) in mixed solution. Infrared spectra indicated that chloridion on the benzene ring was substituted by thiosemicarbazide group. TG and DTG confirmed that TSCIEF was more stable than PP-g-St under the same temperature. The optimum adsorption pH value is 2.
