Abstract
The polypropylene (PP) fibers were chosen as substrate materials. Functional fibers containing iron were prepared by UV irradiation-coordination method, and then Pd/Fe bimetallic composite catalytic fibers were prepared by replacement reaction and used for the removement of N-nitrosodimethylamine (NDMA). The effect of monomer concentration, the pH of the reaction system and reaction temperature on NDMA catalytic degradation was investigated. The results indicate that the degradation rate of NDMA can reach 69.97% when the AA monomer concentration is 20%, which is the best catalytic reduction effect of composite catalytic fiber on NDMA. The pH of solution and reaction temperature can not greatly influence the catalytic reduction of NDMA.
