| Abstract: | 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. |
