Abstract
PURPOSE: To decompose cyanide easily by heating active carbon containing cyanide, up to a specific temperature or higher.
CONSTITUTION: As for waste matter containing alkali metallic cyanide obtained from plating industry and cyanide, such as alkali metallic salt of metallic cyanic complex, waste active carbon is heated, as it is up to ≥200°C and the waste matter being sludgy is heated up to ≥200°C after pulverized granulated carbon is previously mixed with the same. Then, active carbon, etc., after dried is burned, so the cyanide is easily decomposed by the combustion heat.
