Removal of Arsenic in Drinking Water by Iron Oxide-Coated Sand and Ferrihydrite-Batch Studies

摘要

Arsenic, a common toxic element is mainly transported in the environment by water. Arsenic in drinking water is of major concern to many of the water util- ities in the world. Numerous studies have examined the removal of arsenic from drinking water through treatment processes such as coagulation-precipi- tation, reverse osmosis and ion exchange.
