Comparative Study on Adsorptive Removal of Acid Orange from Wastewater Using Activated Carbon and Conducting Polymer
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 9
Abstract
The present study analyses the feasibility of removing Acid Orange7 (AO7) from aqueous solution using two different adsorbents namely Activated Carbon (CAC) and Polypyrrole Polymer Composite (PPC) prepared from Casuarina. Batch mode adsorption studies were performed in order to investigate the adsorption capacities of these adsorbents by varying initial dye concentration, agitation time, temperature and pH. Surface morphology of adsorbent is studied through scanning electron microscopy and surface area analysis was conducted to evaluate surface area, total pore volume and pore diameter. Results reveal that as the amount of adsorbent increases, the percentage removal of the dye also increases. A comparative study on the adsorptive capacities of CAC and PPC were done and it was inferred that PPC had better adsorption capacity than CAC at an initial concentration of 50 mg/L at 30ºC, 35ºC & 40ºC. The adsorption of AO dye onto CAC and PPC follows pseudo second order kinetics and intra-particle diffusion model. Study on the dye by both the adsorbents fits the Freundlich, Langmuir and Dubnin- Radushkevich isotherms well. The carbon embedded in conducting polymer matrix shows better adsorptive properties than activated carbon. The present study confirms the potentiality of an abundant low cost solid waste material and its availability for the removal of acidic dyes from aqueous solution.
