Available in PDF, EPUB and Kindle. Book excerpt: Arsenic(As), one of most toxic contaminants found in water, is well known to have adverse effects on human health, such as skin cancer. The consumption of arsenic contaminated water has led to human health crises in many countries such as Bangladesh, China and even the western USA. The new EPA standard for arsenic in drinking water is 10 [Mu]g/L, and many smaller drinking water treatment plants are in need of additional treatment to achieve this. Recently, many researchers have being trying to find inexpensive and disposable adsorbents for many small-scale water systems or individual ground wells, which are used in most arsenic endemic areas. The adsorption of As(V) using iron and aluminum oxides has been considered as one of the most effective small-scale techniques for arsenic removal. Two types of nonporous adsorbents were used in this dissertation: iron oxide (Fe2O3) from a byproduct of the steel industry, and aluminum oxide (AI2O3) as a chemical powder. Due to their fast adsorption of As(V) anions and low cost, Fe2O3 and AI2O3 were found to be good and inexpensive adsorbents in lowering As(V) initial concentration in drinking water at a lower pH (
