Pradhan, Manas Ranjan (2012) Removal of Hexavalent Chromium from Contaminated Water by Using a Novel Adsorbent; Cerium Based Polyaniline. MSc thesis.
In this work extensive study has been carried out to understand the removal efficiency of chromium (VI) by a hybrid material, cerium based Polyaniline. Among the various techniques, adsorption is one of the most suitable methods which can be adopted to remove hazardous ions from water and waste water. The development of low cost adsorbent is essential for the benefit of the common people. The hybrid material cerium based polyaniline has been synthesized and characterized by XRD, SEM and AAS. Experiments were conducted in batch mode to know the removal efficiency of chromium (VI) by this material as a function of pH, adsorbent dose, temperature, initial concentration and time. The removal efficiency of the hybrid material was 91 % at pH-7, adsorbent dose of 0.08 g/10ml, contact time 50 minutes and temperature 50°C from the aqueous solution having initial Cr (VI) concentration of 10 mg/L. From this study it is infer that this material is having high potential to remove chromium (VI) and other toxic metal which require further study.
