羊栖菜对水环境中Cd~(2+)的吸附特性
|
摘要
以非活性羊栖菜粉为吸附剂,研究羊栖菜对水溶液中Cd~(2+)的吸附特性。结果发现:在最佳吸附pH为5,温度为313.15K,吸附剂浓度为1g/L,Cd~(2+)初始浓度为40mg/L左右时,羊栖菜对镉离子的去除率的最大值为92.54%,且吸附10 min时,即达到最大去除率93.95%;在60 min时,基本达到吸附平衡,羊栖菜对Cd~(2+)的去除具有快速、去除率高的特点。动力学实验数据符合准二级动力学模型,Langmuir对热力学实验平衡数据的拟合较高,最大理论吸附容量为68.49 mg/g。通过方程拟合和SEM分析发现吸附过程发生了离子交换。FTIR分析显示,羟基、羧基等官能团在吸附过程中发挥了作用,通过解吸可以实现羊栖菜粉的再生和循环利用。
The adsorption characteristics of Cd~(2+) in aqueous solution were studied by using inactive Sargassum fusiforme(S.fusiforme)as adsorbent. The results show that the maximum removal rate of Cd~(2+) is 92.54% under condition of the optimum adsorption pH 5, the temperature 313.15 K, the concentration of adsorbent 1 g/L and the initial concentration of Cd~(2+) about 40 mg/L, and when the adsorption is carried out for 10 min, the maximum removal rate is 93.95%, the adsorption reaches equilibrium at 60 min. The removal of Cd~(2+) is rapid and the removal rate is high. The kinetic experiment data conforms to the quasi-second-order kinetics model, Langmuir has a high fitting degree for the equilibrium data of thermodynamic experiments, and the maximum theoretical adsorption capacity is 68.49 mg/g. By means of equation fitting and SEM analysis, it is found that the ion exchange occurs during the adsorption process. FTIR analysis show that hydroxyl, carboxyl and other functional groups play a role in the adsorption process. The regeneration and cyclic utilization of S.fusiforme can be achieved by desorption.
