摘　　要：为筛选出竹炭对龙胆紫溶液中酸性品红吸附的最佳工艺优化条件,采用单因素试验方法,对其进行了试验研究。结果表明:竹炭用量为25mg时,脱色率较好,当竹炭用量大于25mg时,随着龙胆紫浓度的增大,脱色率逐渐降低;最佳吸附时间为4h;在中性条件下竹炭对酸性品红的吸附效果较好;在50℃时,竹炭对溶液中龙胆紫的脱色率约54.6%。In this paper,a single-factor experiment was conducted to gain the optimum conditions for adsorption of acid fuchsin from gentian violet solution by bamboo charcoal.The results show that the better adding mass of the bamboo charcoal is 25 mg.The decolorization rate decreases with the increase of acid fuchsin concentration;The best adsorption time is 4 h.The adsorption properties will be better in the neutral conditions than in the acid and alkaline conditions.When the temperature was 50℃,the decolorization rate reached about 54.6%.
