| 摘 要： | 主要研究了以活性炭作为吸附剂，以孔雀石绿和酸性铬蓝K作为水污染物时吸附条件的改变对活性炭脱色率的影响。／JDA相同质量的活性炭，当孔雀石绿浓度为8．0mg／L，酸性铬蓝K的浓度为16mg／L时，脱色率最大。保持孔雀石绿和酸性铬蓝K溶液浓度不变，活性炭添加量为25mg/L时两者的脱色率达到最好。孔雀石绿的脱色率随着吸附时间的变化比较稳定，酸性铬蓝K的脱色率随着时间的变化不稳定。在上述几种情况下，活性炭对孔雀石绿的吸附性能明显比酸性铬蓝K要好。

| Abstract: | In this paper,the adsorption properties of activated carbon for malachite green and acid chrome blue K in water solution were studied.The results show that the adsorption of methylene blue on bamboo-carbon is easier than that of acid chrome blue K.Adding the same mass of the activated carbon,the decolorization rate reached the maximum when the concentration of malachite green is 8.0 mg/L,and the concentration of acid chrome blue K is 16 mg/L.Maintaining the concentration unchanged,the decolorization rate of malachite green and acid chrome blue K reached the best at the same time when the added activated carbon is 25 mg/L.Along with the changing adsorption time,the decolorization rate of the malachite green has the small changes,but the decolorization rate of chrome blue K becomes unstable. |
