摘要

采用聚丙烯酰胺、甲醛、氢氧化钠、巯基乙酸为原料，制备出重金属絮凝剂巯基乙酰化羟甲基聚丙烯酰胺（MAMPAM），以含Cu²⁺、含腐殖酸（HA）水样为考察对象，研究MAMPAM对单一和混合体系中Cu²⁺、HA的去除性能.结果表明，MAMPAM对单一体系中Cu²⁺和HA均具有一定的去除效果，且Cu²⁺的去除率随着水样初始pH值的增大而升高；pH值为6.0时，Cu²⁺的最高去除率为95.92%，HA的最高去除率为66.98%.MAMPAM处理混合水样时，Cu²⁺和HA的共存会相互促进彼此的去除，具有协同作用；共存的HA对MAMPAM除Cu²⁺性能的促进作用随着水样中HA浓度或pH值的升高而增强，共存的Cu²⁺对MAMPAM除HA性能的促进作用随着水样中HA浓度的升高而增强.

Abstract：

The heavy metal flocculant, named mercaptoacetyl hydroxg-polyacrylamide (MAMPAM), was prepared by mixing polyacrylamide, formaldehyde, sodium hydroxide and mercaptoacetic acid as raw materials, and its removal performance of Cu²⁺ and humic acid (HA) from water samples was investigated. MAMPAM had a certain effect on the removal of Cu²⁺ or HA from the single system contained Cu²⁺ or HA, respectively. The Cu²⁺ removal efficiency increased with the increase of the initial pH value. The highest removal rate of Cu²⁺ and HA reached 95.92% and 66.98% at pH 6.0, respectively, in the single Cu²⁺ or HA system. Moreover, synergistic promotion of Cu²⁺ and HA was observed in the mixture system contained Cu²⁺ and HA. The coexisting HA could promote the Cu²⁺ removal from water samples and the removal efficiency of Cu²⁺ increased with increasing HA concentration or pH value in the mixture system. Similarly, the HA removal by MAMPAM was enhanced due to the coexisting Cu²⁺ and its removal efficiency was also improved when HA concentration increased in the mixture system.

Key words： heavy metal flocculant copper humic acid chelation precipitation synergistic
