OPTIMIZATION OF PROCESS PARAMETERS FOR DYE REMOVAL THROUGH CHITINOUS WASTE BY RESPONSE SURFACE METHODOLOGY

Abstract

Color present in water itself first contaminant and dyes which are harmful for human is a vast problem. Chitinous waste a problem for environment can be an alternative approach for removal of dyes from water. Nanoparticles made up of chitinous waste are used in this study. Chitosantripolyphosphate (CS-TPP) nanoparticles showed prominent result in removal of reactive blue 19 and reactive blue 198 dyes. Both the dyes were totally (100%) removed by the use of CS-TPP. Statistical analysis though Response Surface Methodology (RSM) and Box Behnken Design (BBD) to optimize pH and concentration were also carried out. After optimization it was evaluated that pH 6.5 and higher Chitosan-TPP concentration showed the highest removal of dyes.
