摘　　要：研究了膨胀石墨对酸性媒介深黄GG、酸性嫩黄2G染料废水的吸附脱色作用,探讨了影响吸附的因素,结果表明:膨胀石墨对两种染料的吸附符合Langmuir吸附等温线,吸附速率快,在适宜条件下对两种染料的脱色率达97.9%以上.In this paper,the adsorption and decoloration of the waste water of acidic dye GG and 2G with the expanded graphite was studied. The adsorptive factors were researched. The experiment indicated that the adsorption accorded with the adsorptive isotherm langmuir between the expanded graphite and two dyes. The adsorptive velocity is too fast, the discolored rate of two dyes was 97.9% upwards under the feasible condition.
