Contents of metal cations exchange capacity of ore minerals in ferromanganese micronodules from the Atlantic, Indian and Pacific Oceans, supplement to: Novikov, Georgy V; Sval'nov, Vyacheslav N; Bogdanova, Olga Yu; Sivtsov, Alexander V (2010): Ion exchange properties of manganese and iron minerals in oceanic micronodules.

Results of experimental studies of ion exchange properties of manganese and iron minerals in micronodules from diverse bioproductive zones of the World Ocean were considered. It was found that sorption behavior of these minerals was similar to that of ore minerals from ferromanganese nodules and low-temperature hydrothermal crusts. The exchange complex of minerals in the micronodules includes the major (Na+, K+, Ca2+, Mg2+, and Mn2+) and subordinate (Ni2+, Cu2+, Co2+, Pb2+, and others) cations. Reactivity of theses cations increases from Pb2+ and Co2+ to Na+ and Ca**2+. Exchange capacity of micronodule minerals increases from alkali to heavy metal cations. Capacity of iron and manganese minerals in oceanic micronodules increases in the following series: goethite < goethite + birnessite < todorokite + asbolane-buserite + birnessite < asbolane-buserite + birnessite < birnessite + asbolane-buserite < birnessite + vernadite ~= Fe-vernadite + Mn-feroxyhyte. Obtained data supplement available information on ion exchange properties of oceanic ferromanganese sediments and refine the role of sorption processes in redistribution of metal cations at the bottom water - sediment interface during micronodule formation and growth.
