Removal of dark green PLS dye from textile industrial waste through low cost carbons.

Abstract

Low cost carbons were prepared from Palm nut shells, Cashew nut shells and Broom sticks by Sulphuric acid process and characterised. The activities of these carbons (PNSC, CNSC and BSC) were compared with that of high cost Commercial activated carbon (CAC). The effect of pH, time, carbon dose were examined along with isotherm studies. The application of these carbons were examined on colour removal of Dark green PLS from both effluent samples and synthetic samples. Comparison is made among the carbons for adsorption of the dye. Desorption studies were also carried out along with BDST studies. Mathematical equations have been designed for the wide range of applications.
