| 中文摘要: |
| The process of adsorption of Cu2+, Cd2+ by immobilized marine algae was investigated.It can be noted from the results that, the process for biosorption of heavy metals (copper, cadmium) by immobilized Laminaria japonica can be described by the Banerm model.According to the model, the adsorption rate constant calculated was 0.107 8 and 0.030 28 min-1 for Cu2+ and Cd2+ respectively.The experimental biosorption equilibrium data for Cu2+ and Cd2+ were in good agreement with those calculated by the Langmuir model.The maximum uptake capacity calculated was 83.3 and 112.4 mg/g for Cu2+ and Cd2+ according to the Langmuir model, respectively.The appetency of Laminaria japonica to Cu2+was better than Cd2+. |
