摘要

摘要: 研究了固定化海带吸附含铜、镉溶液过程的影响因素,结果表明,在pH为3.0~5.0时对Cu²⁺保持高的吸附率,在pH为4.0时对Cd²⁺的吸附率达到最大.随着Cu²⁺,Cd²⁺金属离子初始浓度的降低,吸附率有所降低.对Cd²⁺的吸附率均随着温度的升高而变大.随着吸附剂浓度的增大,对Cu²⁺,Cd²⁺的吸附率逐渐升高,与此相反,对Cu²⁺,Cd²⁺的吸附量则逐渐减小.粒径对Cu²⁺的吸附率影响较小,对Cd²⁺的吸附率有较明显的变化.

Abstract: The influencing factors of the adsorption of metal ions by immobilized marine alage were investigated.It can be concluded from the experimental results that,the adsorption efficiency of Cu²⁺ is high during the wide pH range of 30~50;for Cd²⁺,the pH range is narrow,its adsorption efficiency reaches the maximum when pH=4.0.The efficiency of Cu²⁺ and Cd²⁺ decreases as the initial concent ration of Cu²⁺ and Cd²⁺ decreases.The adsorption efficiency of Cd²⁺ increases as the temperature rises.The adsorptionrate increases gradually as the concent ration of the sorbents increases.In contrast,the uptake of Cu²⁺ and Cd²⁺ decreases gradually.The particle size little influences on the adso rption efficiency of Cd²⁺,but influence on of Cu²⁺ is significant.
