摘要

摘要: 研究了固定化海带吸附含铜、镉溶液的过程,结果表明:非活性海带吸附水溶液中铜、镉离子的动力学过程可以用班厄姆吸附速率方程描述,铜和镉的吸附速率常数分别为0.1078和0.03028min^-1;生物吸附过程符合Langmuir模型,根据Langmuir吸附等温模型的计算结果,得到固定化海带对铜和镉离子的最大吸附量分别为83.3和112.4mg/g,海带对铜离子的亲和性比对镉离子强.

Abstract: The process of adsorption of Cu²⁺,Cd²⁺ by immobilized marine alage was investigated.It maybenoted from the results that,the process for bio-sorption of heavy metals(Cu,Cd) by imm obilized Laminaria japonica can be described by the Bangham model.The adsorption rate constant calculated is 0.1078 and 0.03028 min^-1 for Cu²⁺ and Cd²⁺ according to the model,respectively.The experimental biosorption equilibrium data for Cu²⁺ and Cd²⁺ are in good agreement with those calculated by the Langmuir model.The maxim umuptake capacity calculated is 83.3 and 112.4 mg/g for Cu²⁺ and Cd²⁺ according to the Lang muirmodel,respectively.The appetency of Laminaria japonica to Cu²⁺ is better than Cd²⁺.
