KINETIC, THERMODYNAMIC AND ISOTHERM STUDIES ON THE REMOVAL OF MALACHITE GREEN DYE FROM WASTEWATER USING ALPC.
The aim of the present work is to investigate the quantity of removal of Malachite Green dye from aqueous solution using Activated Los Pantanos De Villa Carbon (ALPC). Generally, dyes are used in chemical, textile, paper, printing, leather, plastics and food industries. The need for the treatment of dye contaminated waste water passed out from the industry. In this study, Los Pantanos De Villa Carbon was studied for its potential use as an adsorbent for removal of Malachite Green dye. This study is focusing on various…show more content… Stock solution (1000 mg/L) of MG dye was prepared by dissolving 1000 mg of MG dye in double distilled water. The solution was further diluted to the required concentrations before use. Before mixing the adsorbent, the pH of each MG dye solution was adjusted to the required value by 0.1 M NaOH or 0.1 M HCl solution.
Preparation of Adsorbent: Los Pantanos De Villa was collected from local area of Perambalur district, Tamilnadu, India. It was dried, charred with excess quantity of concentrated sulphuric acid keeping at 120oC for 10 hours. Then the resultant carbon was washed with excess quantity of distilled water and dried at 110oC for 1 hour and the material obtained was soaked in 5% sodium bicarbonate solution and allowed to stand overnight to remove any residual acid. The material was thoroughly washed with hot distilled water until washings were nearly of neutral effect. To eliminate surface groups by thermal activation, the carbonized material was activated at 600 ºC for 6 hrs in a furnace. The resulting carbons were ground in a mill.
Adsorbent…show more content… The surface area of the adsorbent was determined by Quanta chrome surface area analyzer. The pH of aqueous slurry was determined by soaking 1g of biomass in 50 mL distilled water, stirred for 24 h and filtered and the final pH was measured. The physico-chemical characteristics of the adsorbent were determined using standard procedures. The equilibrium MG dye concentration was determined by using UV-VIS Spectrophotometer (Systronics, Vis double beam Spectro 1203). For stirring purpose magnetic stirrer was used. The pH of zero-point charge or pHZPC was determined based on the previous
