【 摘 要 】

Based on the literature search and patent studies, an overview of the purification methods of natural and technical waters from arsenic compounds was made. Promising methods to reduce arsenic concentration in geothermal heat carriers in Kamchatka deposits have been identified with a view to decrease the toxic discharging effect of exhausted solutions on the environment.
