摘要：
研究了褐煤基活性焦对碱性品红和酸性黑两种染料溶液的脱色特性。结果表明,在上述两体系中,吸附时间分别为50、120 min时,脱色率可分别达到95.9%、91.6%;活性焦投加量及染料浓度变化对脱色率产生不同影响;褐煤基活性焦对碱性品红和酸性黑的吸附规律可用拟二级动力学方程及Langmuir方程描述。

Abstract:
The decolorization effects of lignite-based activated coke on two kinds of dye compounds (fuchsin and acid black) have been studied.The results show that in the above two systems,the decolorizing rates are 95.9% and 91.6%,respectively,when adsorption time for fuchsin and acid black is 50 min and 120 min.The decolorizing rate is affected differently according to activated coke dosage and dye concentration.The adsorption process could be de scribed by pseudo-second-order kinetic model and Langmuir equation.
