BATCH ADSORPTION STUDIES ON THE REMOVAL OF AMARANTH RED DYE FROM AQUEOUS SOLUTION USING ACTIVATED TRAPA NATANS PEELSMANINDER SINGH, D.P. TIWARI AND MAMTA BHAGATAbstract One of the escalating necessities of the current period is the removal of harmful industrial effluents. Amaranth red is extensively used anionic azo dye. Amaranth red is employed for wood, resins, textile, paper, and leather colorization. It is also used in sauces, jellies, ketchup and cake decoration as a food additive. In the present study locally available Trapa natans peel powder, in the form of activated carbon was used as an adsorbent. SEM results revealed a highly porous structure detected in activated Trapa natans peel powder (ATNPP) sample. The physiochemical analysis of (ATNPP) sample was performed through XRD and FTIR. BET analysis was performed to detect the surface area was 34.13 m2/g. Various process parameters like consequence of pH, adsorbent dose, contact time, initial dye concentration and temperature were optimized during the research work. Total adsorption uptake using (ATNPP) adsorbent was 86.29 mg/g. Adsorption isotherm data was top fitted to Temkin D-R isotherm and pseudo first order kinetics were followed. The results obtained indicates that (ATNPP) can be a novel adsorbent for amaranth red dye removal. |
