A Study on the Coprecipitation of Arsenite and Arsenate into Calcite Coupled with the Determination of Oxidation States of Arsenic Both in Calcite and Water

摘要

It was found that the amount of arsenite incorporated into calcite is much less than that of arsenate. The result suggests that the sequestration of arsenic by coprecipitation with calcite cannot be an important chemical process under reducing conditions such as in groundwater where arsenite is the dominant arsenic species.
