OPTIMIZATION OF PROCESS PARAMETERS FOR DYE REMOVALTHROUGH CHITINOUS WASTE BY RESPONSE SURFACEMETHODOLOGYJYOTI JUYAL AND SANJAY K SHARMA
Color present in water itself first contaminant and dyes which are harmful for human is a vastproblem. Chitinous waste a problem for environment can be an alternative approach for removalof dyes from water. Nanoparticles made up of chitinous waste are used in this study.Chitosan tripolyphosphate(CS-TPP) nanoparticles showed prominent result in removal of reactive blue 19and 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 thatpH 6.5 and higher Chitosan-TPP concentration showed the highest removal of dyes.
