Full Description

Lafayette College's Civil and Environmental Engineering Program is currentlydeveloping a low cost, reliable, point-of-entry technology to remove arsenic from groundwatersources of drinking water. The technology is a composite sorbent composed of iron hydroxideand activated alumina iron; it has been named, "iron-enhanced activated alumina" (IEAA). TheIEAA has proven to successfully remove arsenic to levels below the maximum contaminant level(MCL) of 10 parts per billion (ppb) recently established by the United States EnvironmentalProtection Agency (USEPA). The research presented in this paper focuses on a betterunderstanding the surface characteristics of the IEAA involved in the removal of arsenic. Includes table, figures.
