The paper points to the presence of heavy elements such as cobalt, nickel, lead and cadmium ratios of small but very harmful to the environment as well as health harmful if used by people for agricultural purposes, etc. This is the heavy elements harmful if it exceeds the limit as it is then used as components of the value after the extract has found these elements mentioned sources such as Ism...

Cobalt demand is increasing due to its key role in the transition clean energies. Although main Co ores are sediment-hosted stratiform copper deposits of Democratic Republic Congo, also a by-product Ni–Co laterite deposits, where extraction efficiency depends, among other factors, on correct identification Co-bearing minerals. In this paper, we reported detailed study mineralisation profiles Lo...

The trace cations could incorporate into the structure of oxidized green rust (Ox-GR), a layered reactive Fe(III) oxyhydroxide formed from rapid oxidation GR, but effects cation incorporation on mineralogical properties and surface reactivity Ox-GR remain unknown. Here, we synthesized Mn- or Al-incorporated by sulfate-bearing GR determined their structure, elemental composition distribution, As...

The title mononuclear cobalt(III) complex, [Co(C(14)H(19)N(2)O(2))(C(8)H(7)O(2))(NCS)], was obtained by the reaction of 2-acetyl-phenol, 2-(morpholin-4-yl)ethyl-amine, ammonium thio-cyan-ate and cobalt nitrate in methanol. The Co(III) atom is coordinated by one phenolate O, one imine N, and one amine N atom of the tridentate Schiff base ligand, two O atoms of the 2-acetyl-phenolate anion and on...

Cobalt(II) and manganese(III) phthalocyanines bearing peripherally and non-peripherally tetra substituted {(2E)-3-[4-(dimethylamino)phenyl]prop-2-enoyl}phenoxy groups were synthesized by cyclotetramerization of the phthalonitrile derivatives and their electrochemical properties were examined using CV and SWV techniques for the first time. The novel compounds were characterized by using IR, (1)H...

A change in the electronic spin state of the surfaces relevant to Li (de)intercalation of nanosized stoichiometric lithium cobalt oxide LiCo(III)O(2) from low-spin to intermediate and high spin is observed for the first time. These surfaces are the ones that are relevant for Li (de)intercalation. From density functional theory calculations with a Hubbard U correction, the surface energies of th...
