摘　　要：活性炭是一种性能优良的吸附材料,在水处理中具有广阔的应用前景。以唐古特大黄茎为原料制备活性炭,在单因素试验的基础上,采用响应面法优化唐古特大黄茎基活性炭对亚甲基蓝的吸附条件。结果表明:在活性炭用量溶液pH值为7.0、吸附温度为40℃、吸附时间为120 min时,唐古特大黄茎基活性炭对亚甲基蓝的吸附量最大,为321.6 mg/g。Activated carbon is a kind of adsorption material with excellent properties,which has broad application prospects in water treatment.On the basis of single factor test,response surface method was used to optimize the methylene blue adsorption conditions of Tanggu Super yellow stem based activated carbon.The results showed that when the pH value of activated carbon solution was 7.0,the adsorption temperature was 40℃,and the adsorption time was 120 min,the adsorption capacity of methylene blue was the highest,which was 321.6 mg/g.
