Reaction of Chromium(VI) with Ascorbate Produces Chromium(V), Chromium(IV), and Carbon-Based Radicals Reaction of potassium dichromate with sodium ascorbate was studied by EPR spectroscopy at room temperature, in 0.10 M N-[2-hydroxyethyl]piperazine-N'-[2-et... DM Stearns,KE Wetterhahn - 《Ch...
Write a balenced ionic equation for the reaction occurring when:(a) the addition of metallic aluminum to a copper(II) nitrate solution results in the precipitation of copper metal and the formation of aluminum ions in solution.(b) metallic copper is added to a dilute solution of nitric acid...
The direct Cr(VI) reduction process by oxalic acid was conducted. The existence of Cr(VI) in the reaction medium was measured by software Visual MINTEQ and the concentration of Cr(VI) was measured by ICP-OES. The results showed that the Cr(VI) was effici
(VI) was prepared dissolving 1.42 g potassium dichromate in the 250 mL of DI water. The lower concentration of the Cr(VI) was prepared by diluting the stock solution. In a typical process, 3.5 mg of the NP-CD were mixed in the 50 mL of different Cr(VI) solutions and ...

Methanal was used as the reductant, and carbon dioxide was the acidulating agent. The influences of reaction temperature, initial pressure of carbon dioxide, isothermal time and methanal coefficient on Cr(VI) reduction were investigated. Experimental results showed that Cr(VI) was reduced to Cr(...
Future development of this process should immobilize the catalyst by embedding it in a porous support. We examined the effect of borate and phosphate buffers (0.1 M) on the reaction kinetics, using ∼50 mg of the RuO2 Adams catalyst. Figure 4a presents the fraction of conversion of ...
Predicting the distribution patterns of soil microbial communities requires consideration of more environmental drivers. The effects of soil micronutrients on composition of microbial communities are largely unknown despite micronutrients closely relatin
