Abstract
Demercurization of solid mercury-containing wastes with the help of oxidizing agents and mercury-removing solution of calcium polysulphide were studied. The major regularities of mercury removal from luminophore (luminescent and compact lamps), granosan and soil were studied. It was shown that this method of mercury removal allows obtaining low-toxic wastes of the 4th class of danger.
