Adsorption techniques for removal of colour from textile effluent

摘要

Textile wastewater includes a large variety of dyes and chemical additions that make the environment challenge for the textile industry not only as liquid waste but also in the chemical composition. Majority pollution in textile wastewater comes from the dyeing and finishing process. The chemical reagents used are diverse in chemical composition, ranging from inorganic compounds to polymers and organic products. This paper reviews various adsorption techniques used for the removal of color from textile effluent.
