Removal of methyl green dye from water by adsorption onto silicon powder

The adsorption process of methyl green on the powder of silicon was investigated, parameters such as pH, time of mixing, dye concentration, temperature were studied. Data were tested for applicability of some isotherms like Langmuir, Freundlich, and Temkin. The adsorption data fitted well to these isotherms. The amount of adsorbate mono layer on silicon was 𝑞max =38.63988 mg/g. Hence, silicon powder could be used as economically and a green adsorbate fore methyl green dye from an aqueous solution.
