Abstract:

Adsorption of ion, nickel, cobalt, and manganese from ocean water by calcareous sediments, diatomaceous ooze, hydrogenous sediments, and red clay was studied under close to natural conditions using a tracer method. It was found that hydrogenous sediments selectively remove manganese from seawater. This may be associated with formation of chemical compounds between manganese and sediment material. It was also found that nickel, manganese, and iron exist in the ocean in several ionic and neutral forms. Cobalt typically present in only one ionic form Co(2+).
