OPTIMIZATION OF ECOLOGICAL AND ECONOMICAL TASKS AT PROCESSING RAW MATERIALS OBTAINED FROM LEWISITE REACTION MASSES INTO COMMERCIAL ARSENIC OXIDE

The paper presents original technical solutions for processing the raw materials ob-tained from the lewisite detoxication products into arsenic (III) oxide. Our optimization of arsenic (V) compounds removal from the system and sodium chloride purification from im-purities of arsenic compounds allow improving the economical and ecological parameters of the whole process of hydrolyzed sodium arsenite (HSA) conversion into arsenic (III) oxide. Our improvement of certain technological operations has made possible to optimize the gen-eral process scheme.

Key words: processing technologies, hydrolyzed sodium arsenite, arsenic (III) oxide, sodium chloride
