Effect of EDTA,fulvic acid and acetate addition on microbial iron reduction in paddy soils;

Now some research said the process of iron oxide anaerobic reduction is mainly a microbial dissimilatory iron reduction.

Especially, the process of iron reduction has not only an important effect on the basic attribute of paddy slurry but also an unusual significance in the way of soil environment chemistry.

This study revealed that ferric oxalate could serve as a better substrate for the ferric reduction by either leaf discs or the membrane bound ferric reductase compared with the other commonly used ferric chelates such as Fe III EDTA and ferric citrate.

Study on preparation of reduced iron powder using copperas;

An experimental study of carbon-reduction process in preparing reduced iron powder using V-Ti magnetite concentrate;

With some domestic hematite and magnetite ores as the raw materials,sponge iron powder with high performance can be obtained adopting Hgans C-H two-stage reduction technique,and hydrogen-reduced iron powder can be prepared after a further hydrogen reduction process.

A novel recovery process for removing NO from flue gas with the recovery process of absorption with acid following complexation with ferrous chelate in aqueous solution and reduction with iron powder was proposed.
