Abstract: In view of the extreme toxicity of arsenic on human and other living organism the U.S. Environmental Protection Agency (U.S. EPA) has fixed the maximum contaminant level (MCL) for arsenic as 10 ppb in drinking water. We now propose a novel method for the treatment of arsenic that is based on emerging ion-imprinting technology. The new product is expected to have the ability to remove both As(III) and As(V) simultaneously from water. Our ongoing experiments indicate that it can remove As(V) very efficiently. Experiments with As(III) are proposed in the near future. Results demonstrate that the ion imprinted polymer (IIP) has the capability to remove arsenic from water to below the U.S. MCL. ICP-OES and FT-IR have been used to analyze arsenic and monitor the IIP synthesis process, respectively. The new IIP is expected to be a very simple, reliable, and cost-effective to remove aqueous arsenic.
