Fate and effects of xanthates in laboratory freshwater systems

Xanthates are mostly of technical significance as samplers of metal sulfides in mining flotation. Alkali-metal-xanthates are stable, crystalline substances. As Xanthates are hydrolyzed by stomach acid, poisoning is mainly caused by the hydrolysis products alcohol and carbon disulfide. Xanthates, however, are known to be strong fish poisons. Recently xanthates are being discussed as helpful agents in environmental protection because of their ability to remove harmful heavy metals from contaminated waters. The present work was undertaken, to provide more information on the fate and effects on aquatic organisms of these environmental chemicals
