Adsorption and oxidation of arsenic(Ⅲ) by Fe-Mn nodules

Fe-Mn nodules collected from the East Pacific Ocean were used for decolorization of a cationic dye methylene blue(MB) in a batch system.

Soil of Fe-Mn nodules background in Litang karst was analyzed.

Deep-sea manganese nodules and new exploration of its processing techniques;

Experiment on preparation of todorokite from nature manganese nodules by hydrothermal treatment;

Determination of 10Be in manganese nodule samples using accelerator mass spectrometry;

Multi walled carbon nanotubes (MWCNTs) were synthesized by the catalytic decomposition of acetylene at 750℃ under atmosphere of nitrogen over powder of manganese nodules directly and palygorskite powder treated with aqueous cobalt nitrate.

Ocean manganese nodules have the potentiality to be the important mineral resources for extraction of non ferrous metals such as manganese,cobalt,nickel and copper.

With the application background of deep sea mineral lifting, this paper studied the pressure loss of solid liquid two phase flow wtih large sized manganese nodules in a vertically arranged lifting pipe.

Redox characteristics between several Fe-Mn nodules in soils and Cr(Ⅲ)(Ⅰ)——Effect of type of Mn oxide mineral and adsorbed ion;

Migration and conversion of Cr (Ⅵ) in Fe-Mn nodule

In this paper, the weight distribution, the colours and the element geochemistry characteristics of Fe-Mn nodules are studied.

Determination of Cu, Co, Ni,Fe, Mn in Ferromanganese Nodules from the Pacific Ocean by Flame Atomic Absorption Spectrometry;

Because the accumulations of marine ores, such as deep-sea ferromanganese nodules and seamount ferromanganese crusts,are very slow, about a few millimeters per million years, the ability of microscopic analysis of trace elements brings the nuclear microprobe a potentiality to obser.
