Application of Taguchi method for optimizing the process parameters for the removal of Chromium(VI) using Sugarcane bagasse

Abstract The aim of the present investigation is to remove hexavalent chromium from artificial effluent by biosorption using sugarcane bagasse and to analyze the result by Taguchi method. L9 orthogonal array was applied as an experimental design to analyse the results and to determine optimum conditions for chromium (VI) removal from aqueous solution. Various operating parameters were selected to study the biosorption for the removal of chromium(VI) from the effluent. The operating parameters such as initial metal ion concentration, pH, dosage of bisorbent and temperature were studied and the significance of the variables was analysed using Taguchi method. Taguchi method is suitable for the experimental design and for the optimization of process variables for the Chromium(VI) removal. Keywords: Biosorption, taguchi design, Chromium(VI) and optimization.
