| Abstract: | 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. |
