Possible Interaction: Copper and Sulfur

“The results showed that, with the supplement of sulfur , the soil pH and activities of soil enzymes (urease, catalase, and sucrase) decreased gradually, and the available heavy metals (Cd, Cr, Zn, and Cu ) in soil showed an upward trend.”

“The observation that certain metals, such as copper , potentiate the smell of sulfur-containing , metal-coordinating odorants led to the hypothesis that their cognate receptors are metalloproteins.”

“The association of copper with sulfur suggests that a sulfur-containing moiety functions in binding copper.”

“Moreover, strong positive correlations were found between copper uptake and concentration of certain elements in the activated char such as phosphorous, sulfur , calcium and sodium.”

“Liver reserves of copper were depleted rapidly when dietary levels of molybdenum and sulphur exceeded 2.7 mg/kg and 3.8 g/kg respectively.”

“Co-application of sulfur and biosolids showed significantly higher sorghum uptake of Cu than application of sulfur to the spiked soil with Cu.”

“We found that organic matter (OM) (increased with biosolids and compost application) and soil pH (dramatically reduced with added sulfur ) highly affected Cu and Zn mobility.”

“ Sulfur quickly reacted with coexisting iron to remove copper , producing chalcopyrite (CuFeS2), cubanite (CuFe2S3) and bornite (Cu5FeS4).”

“In this work, we designed a sulfur-doped Cu2 O-derived Cu catalyst and showed that the presence of sulfur can tune the selectivity of Cu significantly from the production of various CO2 reduction products to almost exclusively formate.”

“This demonstrates clearly that sulfur and copper acted synergistically to promote the selective formation of formate.”

“The solubility of Cu , Cd and Pb was significantly increased with the application of elemental S due to decrease of pH. Faecal coliform number was markedly decreased by addition of elemental sulphur.”

“The sulfur atom in cysteine moieties of N- and C-terminal cysteine-containing tetrapeptides coordinated with copper ions , which then tightly blocked substrate-binding sites.”
