【摘要】 研究了在粘土存在下固定化海藻粉吸附含铅溶液的过程.结果表明:粘土与海藻混合后,对重金属的吸附量随海藻的含量的增加而增加.在pH=5时,最佳的比例为粘土比海藻为1∶4.现场重金属废水处理(Cu2+、Pb2+、Cd2+、Ni2+)的平均吸附率大于70%.更多还原

【Abstract】 The process of adsorption of metal ions by immobilized marine algae with the existence of clay was investigated.It can be noted from the results that,after mixing with clay,the adsorption rate increases rapidly with increasing amount of the marine algae.When pH=5,the best ratio of quantity between the clay and the marine algae is 1∶4 for Pb²⁺.The result of in-situ handling of the waste water containing heavy metals shows that the average adsorption rates of heavy metal ions Cu²⁺,Cd²⁺,Pb²⁺,and Ni²⁺ are all over 70%.更多还原
