| 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 Cu~(2 ) is high during the wide pH range of 3.0~5.0;for Cd~(2 ),the pH range is narrow,its adsorption efficiency reaches the maximum when pH=4.0.The efficiency of Cu~(2 ) and Cd~(2 ) decreases as the initial concentration of Cu~(2 ) and Cd~(2 ) decreases.The adsorption efficiency of Cd~(2 )increases as the temperature rises.The adsorption rate increases gradually as the concentration of the sorbents increases.In contrast,the uptake of Cu~(2 ) and Cd~(2 ) decreases gradually.The particle size little influences on the adsorption efficiency of Cd~(2 ),but influence on of Cu~(2 ) is significant. |
