Abstract

Abstract:

Taking Cu（Ⅱ） removal rate and flocculant yield as the target indicators,chitosan-based heavy metal trapping magnetic flocculant（MC-g-PAM） was prepared.Single factor experiments were used to investigate monomer content,total monomer concentration,photoinitiator concentration and reaction time,and the best preparation conditions for the two floccu-lants were determined.The best synthesis conditions were：Mass fraction of MC-g-PAM was 60%,mass fraction of total mono-mer was 35%,mass fraction of photoinitiator was 0.04%,and reaction time was 1.5 h.At this time,the removal rate of Cu²⁺ and the production yield were 83.52% and 72.94%,respectively.MC-g-PAM had good application prospect in the field of heavy metal wastewater treatment because of its excellent flocculation and chelating properties.

Key words: flocculation, magnetic flocculant, chelating trapping, chitosan
