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%。BrO3- was absorbed by activated carbon that was made from waste tea. Some affecting factors, such as the opti- mum adsorption time, adding amount of activated carbon, pH value of solutions had been studied in detail. The study sug- gested that the time for adsorption equilibrium was 30 minutes, the optimum pH value was 5.0 and the optimum adding amount of activated carbon was 120mg.Under the optimum conditions, the maximum removal efficiency of BrO3- by acti- vated carbon made from tea could reach 86%.
