Improvement on Determination of the Adsorption Value of Activated Carbon on Methylene Blue

Abstract:

Characteristics of absorption of activated carbon on methylene blue were studied. It was demonstrated that adsorption of activated carbon on methylene blue was very stable on monomolecular adsorption and when multimolecular adsorption existed adsorption became to be weak. An improved method was suggested that many samples were tested adsorption of activated carbon on methylene blue in parallel experiment and certain sample was selected to use in next experiment, its color should approximate to the color of 0.4% CuSO₄ but darker slightly and activated carbon loaded methylene blue was added some fresh phosphate buffer solution to desorb methylene blue on the activated carbon, testing absorption value total concentration of methylene blue in the solutionin (merging the first and second experiment) by spectrophotometer, calculating adsorption value on difference method which original volume of methylene blue added subtracts rest of methylene blue in the solution after adsorption. The new method was simple, rapid and easy. word times would shorten obviously.
