| 摘 要： | 通过批式平衡实验考察了各种材质活性炭对MTBE的最大吸附容量以及吸附的影响因素.结果表明各活性炭的吸附能力依次为JHBG1>JHBG2>GCN8303F300>YK>Bamboo,其中2种国产竹炭JHBG1和JHBG2对低浓度污染的地下水处理时的理论耗炭量分别为0.14和0.18g/L;水体中天然有机物对MTBE有一定的竞争吸附,丹宁酸值较大的活性炭比较有利于地下水中MTBE的去除.采用连续流的微型快速穿透实验(MCRB)考察了活性炭的吸附容量利用率,结果证明活性炭吸附可以作为一种有效的地下水中MTBE的去除工艺,这为MTBE污染场地的异位修复提供一个实际可行的参考.

| Abstract: | Methy tert-butyl ether(MTBE),a popular organic solvent and gasoline additive,has become a common groundwater pollutant.Numerous isotherm runs were conducted to evaluate the effects of contact time,initial MTBE concentration,raw material/activation,and solution composition on the adsorptive capacity of granular activated carbon(GAC) for MTBE.The adsorption capacity of the carbons employed was in the order of JHBG1>JHBG2>GCN830-F300>YK>Bamboo.JHBG1 and JHBG2 had the lower consumption amount of activated carbo... |
