摘要
研究马尾藻对污水中重金属铅离子吸附率的影响,通过单因素、正交实验确定。结果表明:当铅离子浓度为120 mg/L时,吸附铅离子的最佳条件为马尾藻用量0.6 g、温度30℃、pH5、吸附时间7min,吸附率达81.21%。
Adsorption of heavy metal ions of lead from aqueous solution by gulfweed was studied by single factor and orthogonal experiments.The results showed that the optimal condition through pectrophotometric method was concentration of lead ion 120mg/L,gulfweed weight 0.6g,temperature 30℃,pH5,time 7.0min,the adsorption rate of Gulfweed reaches 81.21%.
