摘　　要：通过测定在不同的ｐＨ下，活性炭对亚甲基兰吸附量的影响，表明了活性炭表面的ζ电位对亚甲基兰的吸附规律起着重要作用．并进行了活性炭对亚甲基兰在不同ｐＨ值和不同温度下的吸附动力学和吸附热力学参数的估算．进一步揭示了活性炭在不同ｐＨ下对亚甲基兰的吸附机理．The effect of pH on the adsorption of methylene blue on the activated carbon from aqueous solution has been studied.It has been found that the zeta potential of the activated carbon has a great effect on adsorption capacity of methylene blue.The rule of the effect of zeta potential or activated carbon on the adsorption of methylene blue is much the same as the other dyes which we have studied. The kinetic and the thermodynamic parameters of adsorption as a function of pH has been evaluated. The mechanism for adsorption of methylene blue on the activated carbon has also been discussed.
