Structure and Characterization of Strong Acid Cationic Exchange Fiber

Abstract:

A novel polypropylene strong acid cationic exchange fiber (SACEF) was prepared by sulphonation reaction of polypropylene graft styrene (PP-g-St) fiber. The structure of SACEF was characterized through IR, TG, DTG, EA and SEM testing. The physicochemical properties of PSACEF, including adsorption capacity, adsorption dynamics, water content, and regeneration stability were evaluated. The results showed that the adsorption capacity of SACEF was 4.42 mmol·g^-1. Infrared spectra indicated that hydrogen on the benzene ring was substituted by sulfuric acid group. TG and DTG confirmed that SACEF was more stable under the 250 °C. The adsorption dynamics suggested that the adsorption on SACEF was fast and it nearly reached equilibrium within 1 min. The water content of SACEF was 55%~60%. SACEF showed good regeneration performance. The adsorption capacity was constant after being used many times.
