摘要
考察了吸附时间、茶叶渣粒径、温度、铜离子初始浓度、茶叶渣的用量、pH等不同因素对茶叶渣吸附铜离子效果的影响,列出吸附量表格,作出了吸附率曲线。实验结果表明,茶叶渣对铜离子有良好的吸附效果,吸附率最高为84%;茶叶渣粒径和温度较其他因素对吸附的影响更为显著;通过对动力学参数的计算表明,准一级动力学模型拟合后线性相关系数为0.968 6,准二级动力学模型拟合后线性相关系数为0.998 1,准二级动力学模型比准一级动力学模型更适合描述茶叶渣对铜离子吸附的动力学行为。
In this paper, the effect of various parameters such as adsorption time, particle size of the tea leaves,temperature,initial concentration, quantity of the waste tea, pH for adsorption characteris- tics to copper ion by waste tea was studid. The form of adsorbing capacity was listed and the curves of adsorption rate was drawn. The results indicated that waste tea had fine adsorption effects on copper ion, the highest adsorption rate is 84% ;the particle size of the tea leaves and temperature has the greater effect on adsorption effects;kinetic parameters were evaluated and found that the linearly de- pendent coefficient of Pseudo - first - order is O. 9686 and the linearly dependent coefficient of Pseudo - second - order is 0. 9981. Undoubtedly, Pseudo - second - order rate kinetic model showed great correlation.
