| Abstract: | Shanyin county, an area prevalent of endemic arsenic poisoning in Shanxi Province, was selected as the experimental field to verify the methods studied for removal arsenic from dispersed drinking water.The results showed that the desired goal has been achieved from the field study.The results confirmed that arsenate could be removed from drinking water by using ferric sulfate or aluminum sulfate as coagulants and employing sand filtration.Javelle water(sodium hypochlorite) is an effective oxidant for arsenite.The performance of iron oxide coated sand developed in this study was good for arsenic removal.Further study and application is needed. |
