Abstract
In recent years, biosorption has been suggested as being cheaper and more effective than chemical or physical technologies. Low cost, high efficiency, minimization of chemical and biological sludge are the most important advantages of biosorption technique. Moreover, biosorbent regeneration and metal recovery is also possible. In this study, teakwood, neem and rosewood saw dusts were chosen for the adsorption of dyes from the textile effluents. In this work, the effect of contact time, pH, temperature and concentration of the sawdust towards the dyes present in the textile dye effluent were studied in detail. The equilibrium isotherms were analyzed by Langmuir and Freundlich adsorption isotherms. From the results obtained, the neem sawdust showed better adsorption, so it was taken for the analytical studies. The pre-treated neem sawdust and the dyes absorbed by this are investigated using Scanning Electron Microscope (SEM) and Fourier Transform Infra Red (FT-IR) spectroscopy for the surface morphology and surface functional groups. This study therefore shows that neem sawdust could be prescribed as bio-sorbent for the removal of dyes from the industrial effluents. The simplicity of the method may be significant for the treatment of dye waste waters that are difficult to deal with using chemical and biological methods.
