ABSTRACT

The textile industry consumes a substantial amount of water in its manufacturing processes used mainly in the dyeing and finishing operations of the textile plants. The wastewater from textile plants is classified as the most polluting of all industrial sector caused by discharged of untreated effluent into water bodies. In the present investigation dead fungal biomasses from onion isolate is evaluated as a potential biosorbent in the removal of basic blue 9 dye. The choice of onion isolate as a biosorbent for further work was based on its high growth rate as well as high rates of biosorption. Basic Blue 9 dye was chosen as a dye of interest considering its wide use in Indian textile industry and lack of any credible work on them. Experimental design based on sequential statistical approach consisting of Plackett–Burman Design (PBD) for screening critical factors followed by Central Composite Design (CCD) using Response Surface Methodology (RSM) was used for removal of basic blue 9 dye. The use of well-established statistical techniques, to build models, plots, to study the interactions between the variables and to select the optimum conditions of variables and minimizing the errors. Equilibrium and kinetic modeling of biosorption shows that the adsorption follows Langmuir isotherm. Kinetic studies were done using pseudo first order kinetics and pseudo second order kinetics. FTIR analyses indicated that the principal groups involved in sorption were CH and OH. Optimization of biosorption by RSM could achieve 94.16 % of dye removal.
