Preparation of raw oyster shell for removal of crystal violet dye from aqueous solution

Food waste, raw oyster shell were prepared for the adsorption of Crystal Violet dye from the aqueous solution. The adsorption using raw oyster shell were found to be more economical and effective. Various parameters such as the size of adsorbent, adsorbent dosage, initial dye concentration, contact...
