Mechanism of the NiCoFe ternary alloy deposition
… but is enhanced compared with its single metal rate. Both catalytic and inhibiting effects are observed for Co deposition. Such behavior has not been observed before, and is considered unique to the ternary alloy group. The Co rate increases with the Co2+ bulk concentration but is …

Layered Double Hydroxides: Synthesis, Characterization, and Interaction of Mg-Al Systems with Intercalated Tetracyanonickelate(II)
… found it impossible to have both of the required metal hydroxides present simultaneously in the system. An additional synthesis using a halogen as an oxidizing agent also failed to produce material of any characterizable quality.

Oxidation of organic compounds in molten salts
… oxidation of organic compounds in molten alkali metal hydroxides containing manganates. It has been shown that controlled oxidation can be readily achieved with high specificity to give products in high yield with very short reaction times. The concurrent changes in the melt were monitored using …

Development of adsorbent materials for phosphate recovery
… evaluates the synthesis of ZnO-based and layered metal hydroxide adsorbent materials for phosphate recovery. Layered metal hydroxides are analysed due to their metal composition tunability and positively-charged surfaces. In addition, a novel adsorbent synthesis approach was evaluated through the …

Significance of pH and pCl in heavy metal ion reactions and mercury (II) adsorption by soil materials
… of hydroxy and chloride complexes of these heavy metal ions is discussed in relation to solubilities of sparingly soluble salts, Hg(II) adsorption on clays, and Hg(II) interactions with organic functional groups. Occurrence of and competition between Hg(II) hydroxy and chloride complexes is …

Structural Determination of Copolymers from the Cross-catalyzed Reactions of Phenol-formaldehyde and Polymeric Methylenediphenyl Diisocyanate
… of phenolic monomers as perturbed by alkali metal hydroxides in an aqueous environment was studied with 1H and 13C NMR. Changes in electronic structure and thus reactivity were related to solvated ionic radius, solvent dielectric constant, and their effect on ion generated electric field …

An Alternative Method to Concentrate E. coli O157:H7 from Meat Homogenates to Facilitate Detection by Cultural and Molecular Methods
… or becoming clogged with food particulates. Metal hydroxide concentration of bacterial cells has gained increased recognition as a new alternative method to non-specifically concentrate bacteria from foods (Lucore et al., 2000; Cullison and Jaykus, 2002). The objective of this research was to …

The synthesis of calcium phosphate from municipal wastewater and its application for the removal of metals from acidic effluents
… Mg2+, Ca2+, and Mn2+) ions including rare earth metals contained in acid mine drainage (AMD) have strong affinity to phosphate contained in municipal wastewater (MWW). Therefore, their sequential treatment could be feasible, particularly when viewed under reuse, recycle, and resource recovery …

An investigation into the effects of pulp chemistry under wet and dry grinding on the flotation response of pyrite
… ores in order to meet the growing demand for metals and metal products. Therefore, it is of paramount importance to have a fundamental understanding of minerals processing operations in order to improve the recoveries of valuable metals on an industrial scale. It has been acknowledged that the …
