Abstract

The investigation focused on the adsorption of the blue methylene on banana peels powder The studies led to determine contacting time 40 minutes for 90 elimination of substrate methylene blue However this contacting time can vary with dye concentration The optimization of parameter such as the temperature agitation and initial concentration of dye has showed a sensitive improvement of the capacity and rate adsorption Moreover the adsorption of this compound is well described by both Langmuir and Freundlich isotherm models
