Abstract
In a method of preparing an immobilized selenium system or body, a selenium-carbon-oxygen mixture is formed. The mixture is then heated to a temperature above the melting temperature of selenium and the heated mixture is then cooled to ambient or room temperature, thereby forming the immobilized selenium system or body.
