Abstract: “Release of coloured textile effluent in to aquatic environment is detrimental as they prevent penetration of light in to water, thereby affecting aquatic life and creates harmful water. Biosorption is an alternative treatment available other than physicochemical and biological methods to treat these toxic effluents. This study investigates the potential of water hyacinths to adsorb hazardous azo dye metanil yellow from aqueous solution. Metanil Yellow, is a widely used toxic dye containing one or more azo bonds (-N=N-). Metanil Yellow is used in number of industries such as textile, dyeing, food, cosmetics, paper printing industries and with textile industries as large consumers. Biosorption process was carried out using immobilized dead aquatic weeds. The influences of adsorption parameters such as initial dye concentration, pH, contact time, adsorbent dosage, agitation speed, and temperature were evaluated and optimized. Further the mechanism of biosorption earned good fits for Langm”
