A coprecipitation of copper(II) and zinc(II) from complex sulfate solutions with natural calcite was investigated. The main features of the process and mineral forms of incorporation of heavy metals in a solid phase were determined. Sequential precipitation proceeds at pH 5.3–5.5 and 6.5–7.0 ...
Case Report: An 86-year-old woman accidentally ingested a preparation containing zinc and copper sulfate. At ninety minutes after ingestion, the peak plasma concentration was 1979 g/dL for zinc and 209 g/dL for copper, suggesting preferential absorption of zinc. The major complications were gastri...
The meaning of COPPER SULFATE is a sulfate of copper; especially : the normal sulfate that is white in the anhydrous form but blue in the crystalline hydrous form CuSO4·5H2O and that is often used as an algicide and fungicide.
英文名称Copper(II) sulfate pentahydrate 储存温度室温 运输条件常规运输 产品介绍 五水硫酸铜(II)是一种常用的路易斯酸催化剂,用于促进酸催化的有机转化。它也可与其他混合氧化剂共同组成有效的氧化还原催化剂。 应用 五水硫酸铜(II)可用作催化剂: 在乙酸酐环境下,进行醇和酚的乙酰化反应。
摘要: ► Cu is efficiently leached from copper-zinc waste by H2SO4 solutions with Fe3+ ions. ► Fe3+ ions inhibit zinc and iron leaching from converter slag flotation tailings. ► Copper and zinc leaching is controlled by chemical reaction on the particle surface....
A full-length cDNA of 803 base pairs encoding a putative copper/zinc−superoxide dismutase (Cu/Zn-SOD) from Epinephelus malabaricus was cloned by the polymerase chain reaction approach. Nucleotide sequence analysis of this cDNA clone revealed that it comprises a complete open reading frame coding ...
Dietary CuSO(4) inhibited the coliforms and thus potential pathogens as well, but overall the observed effect of CuSO(4) was limited compared to that of ZnO. 展开 关键词: Enterococcus, piglets, intestinal microorganisms, copper sulfate, feed intake, species diversity, stomach, lactic acid ...
Cupric sulfate, a bluish crystalline powder, also known as hydrocyanite and copper sulfate, vitriol, chalcanthite, and bluestone, is an azure blue material used in the It is used in the leather industry. It is prepared by the reaction of sulfuric acid and copper. It is also obtained as ...
A process for separating zinc and copper values from an aqueous solution of copper and zinc salts having a pH of between about 0. 5 and 6 is provided comprising:A. CONTACTING SAID AQUEOUS SOLUTION WITH THE COPPER SALT OF DI-(2-ETHYLHEXYL) PHOSPHORIC ACID TO FORM A ZINC- CONTAINING ORGANIC...
