NOVEL MATERIALS FOR ARSENIC REMEDIATION
This paper reports the application of two novel materials, Spherical Activated Carbon (SAC) and Processed Iron Waste (PIW), along with the existing materials, hematite and Granular Activated Carbon (GAC), for the removal of sodium arsenate and mixture of arsenic (III) and arsenic (V) from water. Results of static adsorption studies carried out in the laboratory have shown higher efficiency (almost hundred percent removal of arsenic from water) of SAC and PIW compared to hematite and GAC. Effect of various parameters such as adsorbent dose, contact time and initial arsenic concentration is presented. These studies will prove beneficial in the development of treatment technology (plant / filter) for arsenic-contaminated ground water.
