茶叶活性炭吸附处理溴酸根优化条件研究
|
摘要
利用废弃茶叶制备的活性炭吸附水中的溴酸盐,探讨不同条件下茶叶活性炭对溴酸根的吸附效果。结果表明:在吸附时间为30min,溶液p H值为5.0,活性炭投加量为120mg的条件下,茶叶活性炭对溴酸根的吸附效果最好,吸附去除率可达86%。
BrO_3-was absorbed by activated carbon that was made from waste tea. Some affecting factors,such as the optimum adsorption time,adding amount of activated carbon,p H value of solutions had been studied in detail. The study suggested that the time for adsorption equilibrium was 30 minutes,the optimum p H value was 5.0 and the optimum adding amount of activated carbon was 120 mg.Under the optimum conditions,the maximum removal efficiency of Br O_3- by activated carbon made from tea could reach 86%.
