摘要
为开发新型的污水处理用活性炭提供理论依据,采用C15型木质活性炭吸附废水中的铬(Ⅵ),考察了不同吸附条件对吸附效果的影响。结果表明,C15型木质活性炭在吸附时间为6.0h、pH值约大于4的条件下,对废水中铬(Ⅵ)有较好的吸附效果,铬(Ⅵ)初始浓度越高,活性炭对铬(Ⅵ)的吸附量越大。
In this paper,C1 5-type wood-base activated carbons were used to remove Cr（Ⅵ）in wastewater. Spectrophotometry was applied to measure the adsorption capacity of Cr（Ⅵ）.The effects of different adsorption conditions on the adsorptive performance were studied to provide theoretical basis for development of new acti-vated carbon for wastewater treatment.The results indicated that,C1 5-type wood-base activated carbons had good adsorption performance under adsorptiom time of 6.0 h,pH value of more than 4,the higher initial concen-tration of Cr（Ⅵ）,the larger adsorption capacity of Cr（Ⅵ）.
