Low-Cost Technique of Arsenic Removal from Groundwater with Underlying Mechanism

CB Tiwary, Shyam Natayan Singh, and BN Singh

This research examines the potential of removing arsenic from water by Co precipitation with naturally occurring iron. This study examined the sensitivity of arsenic removal in response to manual mixing and prolonged settlement. It was observed that 24 h settlement could achieved about 88% arsenic from polluted water. It has also demonstrated that arsenic mixed with iron level (1.2 mg/l) Shaking in container and 3 days settlement could reduce the arsenic concentration from 0.10 mg/l to standard 0.05 mg/l. There was evidence that absorption may be the effective trapping mechanism when Fe/As weight ratio was ï�?³ 10.
