ADSORPTION ISOTHERMS, KINETICS AND THERMODYNAMICS OF METHYLENE BLUE DYE ONTO ACTIVATED PERGULARIA DAEMIA CARBONAravinthavathani S., Arivoli S., Hema M. and Ajithkumar M.Abstract The research of the present work was to investigate the removal of Methylene Blue dye from aqueous solution by using Activated Pergularia daemia Carbon (APDC). Generally, dyes are used in chemical, textile, paper, printing, leather, plastics and various food industries. The need for the treatment of dye contaminated waste water passed out from the industry because it causes determent problems to human beings and animals. In this study, Pergularia daemia Carbon was studied for its potential use as an adsorbent for the removal of Methylene Blue dye. The various factors affecting adsorption, such as initial dye concentration, contact time, adsorbent dose, effect of temperature and pH were evaluated. The experimental data were fitted into the pseudo-second order kinetic model. The equilibrium of adsorption was modeled by using the Langmuir and Freundlich isotherm models. The objective of the present work suggests the APDC may be utilized as a low cost adsorbent for Methylene Blue dye removal from the aqueous solution. |
