Crystallisation of Barium Chromate
… of low solubility materials were studied, Barium chromate being chosen as a typical one. The increase in solubility in acid solution was examined. Also the solubility of Barium chromate in the Presence of other compounds (Urea, complexing agents) was Studied. Conditions of supersaturation were …

Growth Rate of Barium Chromate Crystals.
The crystallisation of barium chromate was investigated with theobjective of producing crystals of 10-4m in size instead of thecommercially available size of 2 x 10--6m. This was achieved by themethod of controlled homogeneous precipitation from solutions oflow pH. However, this was not an optimum …

Phosphate stabilization by non-chromate post-rinse treatment
… which contains certain anions or cations. Chromatepost-rinse treatment is the most widely used method and has shown a great improvement in corrosion resistance. But, due to the environmental problems caused by chromate ions, non-chromate post-rinse treatment should be developed, which has …

Formal Potential of the Chromate-Chromic System in Sulfuric Acid
Since the value of the formal potential of the chromate-chromic half-cell would be of considerable interest and since very few measurements of this potential were found in literature, an investigation of its determination was undertaken. The usual concept of formal potential is the potential value …

RESPONSE OF A NEIL1 DEFICIENT MURINE EPITHELIAL CELL LINE TO CHROMATE
… the ease with which it can be taken into a cell. Chromate, Cr(VI), ions are taken up by a cell through relatively non-selective anion channels which normally regulate uptake of phosphate and sulfate ions. Once in the cell, chromate ions are reduced by intracellular reductants such as ascorbate and …

Effectiveness of Non-Chromate Inhibitors on Preventing Corrosion of Aluminum Alloys
… studied using a radioactive labeling method. Chromate and phosphate adsorption data enhances the information gained from localized dissolution studies. The effectiveness of pertechnetate as a corrosion inhibitor for aluminum alloys has been investigated through radiometric adsorption studies. …

Characterisation of Schwertmannite - Geochemical Interactions with Arsenate and Chromate and Significance in Sediments of Lignite Opencast Lakes
… systems. By means of the anions arsenate and chromate, the uptake capacity by adsorption or substitution and consequential changes in crystal structure were characterised. Additionally, a possible re-mobilisation of these compounds was investigated because the metastable schwertmannite easily …

Dry magnetic assisted impaction mixing of sub-micron boron and barium chromate for a time delay composition
… the mixture homogeneity of, Boron and Barium Chromate, a delay composition called T-10, using a novel dry mixing technique, , called the Magnetic Assisted Impaction Mixing (MAIM). Two additional mixing methods, ultra-sonic mixing and shaker mixing (dry and wet), were used for comparative …

Molecular mechanisms of the carcinogen chromium(VI)-induced DNA-protein crosslinking in cultured intact human cells
… Carcinogenicity. However, the mechanism of chromate-induced DNA-protein crosslinking has not been established. Based on the current literature and our preliminary data, we hypothesized that Cr(VI)-induced DNA-protein crosslinks may, in part, be due to generation of active oxygen species …

Determining the differences in effect of chromate, chromite and chromium picolinate in rainbow trout (Oncorhynchus mykiss) at environmentally relevant concentrations
The Ring of Fire is a region in the James Bay Lowlands of northern Ontario that houses a rich deposit of chromite and is slated for mining development. The goals of this study were to better understand the relative effects of Cr6+ to Cr3+ in rainbow trout, identify potential protein biomarkers to …

Studies on the biotransformation of chromium (VI) by methane oxidising bacteria.
… phosphate moieties. BLAST searches using known chromate (Vl)-reducing enzymes from other bacteria indicated the presence of five potential chromate reductases in the genome sequence of M. capsulatus (Bath). Detailed bioinformatic analysis, including molecular modelling, indicates a possible mode …

Oxyanion Adsorption by Iron and Ruthenium Oxides: A Macroscopic, Spectroscopic, and Kinetic Investigation
… is specifically adsorbed the ruthenium oxide Chromate adsorption on ruthenium oxides was investigated as a function of pH and chromate solution concentration. Macroscopic adsorption studies and zeta measurements suggest chromate forms an inner-sphere surface complex with both oxide X-ray …
