Nowadays, acid mine drainage (AMD) is one of the most important problems in coal mine contamination. The Karmozd coal mines in Mazandaran Province are one of the largest and oldest coal extractions in Central Alborze Coal Basin. The samples of coals, host rocks, mine drainages and secondary surface minerals have been collected in summer season of 2005. On the basis of hydrogeochemistry studies ...
To facilitate the study of individual metal binding sites of polymeric metalloproteins, conversion of exchange-labile Co(II) in E. coli alkaline phosphatase (EC 3.1.3.1) to exchange-inert Co(III) was examined. Oxidation of Co(II) alkaline phosphatase with hydrogen peroxide results in a single absorption maximum at 530 nm and loss both of the characteristic electron paramagnetic signal and of en...
Enantiomerically enriched coordination compounds of aspartic acid and racemic mixtures of coordination compounds of glycine metal-ligand ratio 1 : 3 were synthesized and characterized using infrared and UV-Vis spectrophotometric techniques and magnetic susceptibility measurements. Five of the complexes were resolved using (+)-cis-dichlorobis(ethylenediamine)cobalt(III) chloride, (+)-bis(glycina...
Cobalt-iron oxyhydroxides (CoFeOOHx) are among the most active catalysts for oxygen evolution reaction (OER). However, their redox behavior and electronic chemical structure of sites still ambiguous. To shed more light on this, complete rapid reconstruction four helical cobalt-iron borophosphates with different Co:Fe ratios into disordered can be achieved, which electrolyte-penetrable thus tran...
