Abstract

Hydrolytic sodium arsenite (HSA), a product of chemical weapons destruction, contains a significant amount of arsenic, which can be used for the growth of single crystals and epitaxial layers of AIIIBV-type semiconductors and solid solutions based on them. A process is proposed for producing an arsenic acid solution from HSA using a highly concentrated hydrogen peroxide solution as an oxidizing agent. This technique can be applied in the 6N purity arsenic production.
