Removal of methylene blue dye in aqueous solution by pretreated eggshells waste

Dye wastewater presents high impact to aquatic environment due to its toxicity, non‐biodegradability and resistance. Chicken eggshell is one of the abundant inexpensive waste materials which can be applied successfully as a biosorbent for removal of various pollutants. The aim of this study is to investigate the efficiency of differently prepared chicken eggshell for removal of methylene blue dye from aqueous solution. The results of this study suggested that the chemically activated eggshells can be effective adsorbent for removal of the methylene blue dye from aqueous solution.
