TiO_2复合吸附剂去除三氯甲烷的试验研究

Study on removal of trichlormethane by titania compound adsorbent

采用TiO2复合吸附剂进行了消毒副产物三氯甲烷的去除试验,考察了吸附时间、吸附剂用量、溶液pH等因素对试验的影响,并与活性炭吸附法进行了对比。结果表明,当三氯甲烷的浓度为100μg/L时,经TiO2复合吸附剂在一定条件下处理后,去除率达98%,高于或相当于颗粒活性炭吸附法的处理效果。

Test was conducted for the removal of CHCl3 by titania compound adsorbent,and compared with active carbon adsorbent.Factors influencing the test,such as adsorbing time,quantity of the adsorbent and pH of the solution were investigated.The results show that absolute concentration is below 10 μg/L and the removal rate of chloroform reaches 98% in a water sample with CHCl3 concentration of 100 μg/L and with the treatment of titania compound adsorbent,which is equal to or obviously higher than active carbon adsorbent.
