Abstract
A method for preparing an adsorbent for removing organic dyes from water includes reacting egg white with hydrochloric acid. The reaction can include mixing egg white with water to form a solution, and adding the acid to the solution to form a precipitate. The precipitate can be filtered, washed, and dried to provide the adsorbent. The adsorbent can be contacted with wastewater contaminated with organic pollutants to remove the organic pollutants from the wastewater. The organic pollutants can include p-nitrophenol.
