This thesis was conducted for evaluation of sugarcane bagasse as bio adsorbent for removing ofrntextile wastewater colour. The sugarcane bagasse was soaked in hydrochloric acid solution forrntwenty four hours and finally the sugarcane bagasse was dried in oven to remove moisture. Thernsugarcane bagasse was characterized according ASTM method for moisture content and ashrncontent as well as according ISO method for volatile matter. The experimental result obtainedrnwere 29% for moisture content, 4.2% for ash content and 83% for volatile matter. FTIR analysisrnof sugarcane bagasse was carried out and the experimental result indicates that the presence ofrndifferent functional groups on the surface of sugarcane bagasse before and after adsorption. Inrnaddition to this XRD analysis of sugarcane bagasse was conducted. The higher peak of XRDrnanalysis indicates crystalline cellulose region and the lower peak indicates amorphous structure.rnThe raw textile wastewater was characterized according APHA method for BOD, COD and TDSrnbefore and after adsorption as well as pH before adsorption and the results were for BOD itrnranges from 48 mg/L â€“ 163 mg/L before adsorption and from 20 mg/L â€“ 83 mg/L afterrnadsorption and for COD 925 mg/L before adsorption and 50 mg/L after adsorption as well asrnTDS 10,000 mg/L before adsorption and 8400 mg/L after adsorption. Eventually the pH valuernbefore adsorption was 9.65. Adsorption was conducted using synthetic azo dye and textilernwastewater at the factors of concentration, Adsorbent, pH and contact time and the higherrncolour removal was achieved at optimum value of concentration 52.5 mg/L, dose of adsorbentrn2.5-gram, pH 6.5 and time 75 minute for both adsorption. Based on ANOVA analysis onrnadsorption of azo dye and textile wastewater on to bagasse, factors of concentration, pH, andrntime were significant. Kinetic study was carried out for adsorption of azo dye and textilernwastewater and pseudo first order model was well fitted for both adsorptions. In addition to thisrnadsorption isotherm was conducted for azo dye and textile wastewater adsorption and thernLangmuir isotherm model was well fitted for both adsorptions. To conclude the comparativernanalysis of azo dye and textile wastewater adsorption using sugarcane bagasse as bio-adsorbentrnand the result provide that, there was a higher percentage of colour removal with azo dyernadsorption when compared with adsorption of textile wastewater and the results were 90% forrnazo dye colour removal and 81% for textile wastewater colour removal.
