Dyeing of Waste Cotton Fabric as Biosorbent of Heavy Metals from Aqueous Solution

Heavy metal pollution is a major problem in the environment. The impact of toxic ions can be minimized by different technologies. But among them, adsorption was found to very efficient and common due low concentration uptake economically feasible properties. Cotton fabrics are cost widely used, promising for future. These available abundant quantity, cheap have or little economic value. Waste cotton (WCF) used detoxifications water waste as absorbent sorption Ca (II)and Mg (II) from aqueous solution. . were characterized before after process. fabric has been two directions removal heavy metals dyeing .The results maximum capacity 42 mg g−1 35 at optimal pH (11). behavior WCF (WCF-Ca (ll)) with reactive yellow145 (RY 145 ) studied build up dye, measured exhaustion percentage (E%) ( K/S ). overall fastness properties light, perspiration, washing colored samples ranging good excellent. this study shows significant benefit eco–friend cost-efficiency potential river pollutions comparing traditional adsorbents.
