An efficient removal of crystal violet dye from waste water by adsorption onto TLAC/Chitosan composite: A novel low cost adsorbent

A composite of Typha latifolia activated carbon (TLAC) (a novel, low cost absorbent) and chitosan (TLAC/Chitosan composite) was prepared. The composite was characterised using IR spectra, XRD, FESEM and Pore size studies. Its effectivity was tested for the removal of crystal violet dye from aqueous...

Description
Summary:A composite of Typha latifolia activated carbon (TLAC) (a novel, low cost absorbent) and chitosan (TLAC/Chitosan composite) was prepared. The composite was characterised using IR spectra, XRD, FESEM and Pore size studies. Its effectivity was tested for the removal of crystal violet dye from aqueous solutions. The effect of pH, dose rate and initial dye concentration was evaluated. The adsorption isotherm, kinetics and thermodynamic parameters were studied. Langmuir and Freundlich isotherm models were found fit effectively for the dye adsorption data in the present study. The adsorption followed pseudo-second order kinetics. The evaluated thermodynamic parameters show a spontaneous and exothermic reaction. Overall, this study indicates TLAC/Chitosan composite as an effective adsorbent for the removal of crystal violet dye from aqueous solutions.
