Selective chemical leaching of cadmium, copper manganese and iron in marine sediments.

Abstract

The selective chemical leaching of cadmium, copper, manganese and iron from various minerals has been examined in the laboratory experiment. And the selective leaching technique has been applied to marine sediments to elucidate the role of clay minerals as a scavenger chiefly for cadmium in the sea. The obtained results show that clay minerals assume some significant role for the removal of cadmium from seawater.
