摘要
采用 4种活性炭纤维 ( ACF)作为吸附剂 ,对水中 CHCl3、CCl4、高锰酸钾指数 CODMn、紫外吸光值 EUV2 54等有机微污染物的去除进行了初步研究 ,并与 ZJ- 1 5型颗粒活性炭 ( GAC)进行了对比 .吸附等温线的结果表明 ,ACF3对 CHCl3的去除效果最好 ,当 CHCl3的平衡浓度为 60μg· L- 1 时 ,ACF3对 CHCl3的吸附容量为 2 1 2μg· g- 1 ;GAC对 CCl4的去除效果最好 ,当 CCl4的平衡浓度为 3μg· L- 1时 ,GAC对 CCl4的吸附容量为 0 .83μg· g- 1 ;GAC及 ACF1对 CODMn、EUV2 54有较好的去除效果 ,当CODMn的平衡浓度为 2 .5mg· L- 1 时 ,GAC及 ACF1对 CODMn的吸附容量分别为 2 .1 6mg· g- 1 和 1 .98mg· g- 1 ,当 EUV2 54的平衡浓度为 0 .0 5时 ,GAC及 ACF1对 EUV2 54的吸附容量分别为 0 .32 g- 1和 0 .1 5g- 1 .
The removal of micropollutants in water such as CHCl 3,CCl 4,COD Mn and E UV254 by four type of activated carbon fiber(ACF)was studied in the paper and also compared with ZJ 15 type GAC.Absorption isotherm results show that good removal efficiency of CHCl 3 can be obtained by ACF3 and its absorption capacity is 212μg·g -1 when the equilibrium concentration of CHCl 3 is 60μg·L -1 .Good removal efficiency of CCl 4 can be obtained by GAC and its absorption capacity is 0.83μg·g -1 when the equilibrium concentration of CCl 4 is 3μg·L -1 .Good removal efficiency of COD Mn and E UV254 can be obtained by GAC and ACF1.The absorption capacity of GAC and ACF1 for COD Mn is 2 16mg·g -1 and 1 98mg·g -1 respectively when the equilibrium concentration of COD Mn is 2 5mg·L -1 and for E UV254 is 0 32 g -1 and 0 15 g -1 respectively when the equilibrium concentration of E UV254 is 0 05
