Removal of Arsenic from Liquids

摘要

This disclosure provides methods for separation of arsenic, in the form of arsenate and arsenite, from liquids. The method uses CuO as an adsorbent and brings down the arsenic content of liquids, such as water, to less than 10 ppb. This process is cost-effective and applicable for small, medium, and large scale.

主权项

1. A flow-through process for separating arsenite and/or arsenate from a liquid, comprising:
i) passing the liquid through a composition comprising CuO; and ii) providing a liquid comprising a level of arsenite and/or arsenate of at most 10% of the level of arsenite and/or arsenate in the liquid before step i).
