  • Arsenic sorbent for remediating arsenic-contaminated material
    Patent number: 8227378
    Abstract: An arsenic sorbent includes monohydrocalcite that has been precipitated by mixing an aqueous solution of a soluble carbonate or a carbonate with an aqueous solution that includes an Mg2+ ion and a Ca2+ ion in a ratio “Mg/Ca” of 0.3 or more, the monohydrocalcite having a molar ratio “Mg/(Ca+Mg)” of 0.1 or less. The arsenic sorbent exhibits a high arsenic sorption ability, and can stably retain a sorbate. A purification method using the same is also disclosed.
    Type: Grant
