Abstract: The present research work was to compare the biosorption potential of two natural potential biosorbents. The stem portion of the plants namely Musa paradisiaca and Nymphaea nouchali were used for this study. The textile effluent was made to interact with the biosorbents in the aerobic sequential batch reactor (ASBR). Various operational parameters like pH, temperature, dye waste water to water ratio, and mixed liquor volatile suspended solids were optimized using the Box-Behnken design. The responses were recorded as percentage decolorization and percentage COD reduction. Of the two natural biosorbents, Musa paradisiaca showed the best biosorption potential. The R-sq and R-sq(adj) for percentage decolorization of Musa paradisiaca are 65.58% and 25.42%. And R-sq and R-sq(adj) for percentage COD reduction of Musa paradisiaca are 71.16% and 37.50%. The R-sq and R-sq(adj) for percentage decolorization of Nymphaea nouchali are 62.25% and 18.20%. The R-sq and R-sq(adj) values for percentage COD reduction of Nymphaea nouchali are 61.88% and 17.41%.
