试验采用 4种活性炭纤维 (ACF)和 1种GAC在 30 8K条件下对三氯甲烷和四氯化碳进行吸附速率和吸附等温线研究。此外 ,就四氯化碳的不同初始浓度对吸附等温线的影响也进行了研究。结果表明 ,在吸附低浓度 (× 10 - 3mg/L级 )的卤代烃时 ,活性炭纤维ACF与GAC相比无论在吸附速率还是吸附容量上都具有优势 ,这使得低浓度的污染物能被进一步去除 ,而且设备装置可以更小型化 ,节省投资
The adsorption rate and adsorption isotherms of chloroform and carbon tetrachloride (CCl 4) were studied under the conditions of 30 8 K using four kinds of activated carbon fibers (ACF) and one kind of GAC. In addition, the effect of different initial concentrations of carbon tetrachloride on the adsorption isotherms was also studied. The results show that activated carbon fiber (ACF) has an advantage over GAC in both adsorption rate and adsorption capacity when it is adsorbed at low concentrations (× 10-3 mg / L) of halohydrocarbons. This allows low concentrations of contaminants to be Further removal, and equipment can be more miniaturized, saving investment
