摘　　要：从海藻中提取海藻酸钠,并与腐殖酸钠联用处理含Cd(Ⅱ)、Cu(Ⅱ)重金属的废水,通过改变海藻酸钠-腐殖酸钠水处理剂投加量及溶液pH值、搅拌时间等因素的实验分析,研究了该处理剂对Cd(Ⅱ)和Cu(Ⅱ)的去除效果.结果表明,该处理剂能有效地去除Cd(Ⅱ)和Cu(Ⅱ)等重金属离子,Cd(Ⅱ)去除率大于95.6%,Cu(Ⅱ)去除率大于99.6%.Sodium alginate was derived from algae and associated with sodium humate to deal with the waste water containing copper （Ⅱ） and cadmium （Ⅱ）. The experiment change about the adding amount of sodium alginate and sodium humate, acidity and mixing time was analyzed. The influential factors to the removing rate of the treatment reagents on the copper （Ⅱ） and cadmium （Ⅱ） were also studied. The results showed that the treating reagents could availably wipe off the copper （Ⅱ） and cadmium （Ⅱ）. The removal rate of the cadmium （Ⅱ） was more than 95.6 % , and the removal rate of the copper （Ⅱ） was more than 99.6 %.
