茶树修剪枝制备Cr(Ⅵ)吸附材料及其应用效果

Preparation of Cr(Ⅵ) Adsorbent by Tea Pruned Branches and Its Application Effect

为探索防治水体中重金属污染的方法,本文采用茶树修剪枝制成吸附材料,研究其对水体中Cr(Ⅵ)的吸附效果。结果表明,茶树修剪枝所制作的吸附材料对Cr(Ⅵ)吸附的较优条件为茶树修剪枝用量2 g、吸附温度25℃、吸附时间90 min、pH=2,此时吸附率可达72.63%。其具有较好的吸附效果,可用于治理污水工程,有利于进一步扩展茶树资源的合理利用途径。

In order to explore the control method for heavy metal pollution in water,this paper used tea pruned branches to prepare Cr(Ⅵ)adsorbent,and studied its adsorption effect on Cr(Ⅵ)in water.The results showed that using tea pruned branches to prepare adsorbent,the optimal conditions for Cr(Ⅵ)adsorption were the amount of tea tree pruned branches of 2 g,the adsorption temperature of 25℃,the adsorption time of 90 min,and the pH=2.The adsorption rate could reach 72.63%.It has good adsorption effect,could be used in sewage treatment projects,and help further expand the rational use approach of tea tree resources.
