Effect of Copper Ions on Deep Removal of Cobalt from Zinc Sulfate Solution铜离子在硫酸锌电解液深度净化除钴中的作用硫酸锌电解液除钴Cu2深度净化对Cu2+在湿法炼锌浸出液锑盐法深度净化除钴过程中的作用进行了研究.考察了钴离子浓度达到深度净化浓度(Co2+]<0.1 mg/L)的时间,低于该浓度的持续时间及所需初始...
In the present investigation, the effect of copper inclusion on structural, optical and electrical properties of spray deposited ZnO thin films is studied. The X-ray diffraction studies showed that the films are polycrystalline in nature with hexagonal structure. The optical studies revealed that the...
With mercury a little of the oxyhaemoglobin is altered and with copper it is all changed to a parahaematin type of compound. Globin can be precipitated with zinc, mercuric and copper salts without undergoing any change that affects its ability to form methaemoglobin. The methaemoglobin from ...
memory-switching electronics, superionic batteries, catalysis, smart electronic devices, and magnetic information storage11,12,13. Cobalt (Co2+/Co3+) and copper (Cu+/Cu2+) ions are of the most distinctive transition metal ions in enhancing the properties of various glass networks. The formation ...
Effect of Cu^(2+)ions on bioleaching of marmatite 来自 掌桥科研 喜欢 0 阅读量: 65 作者:陈松,覃文庆,邱冠周 摘要: 铁闪锌矿的 bioleaching 上的 Cu2+ 离子的效果通过饮料沥滤被调查实验.接种的细菌是 Acidithiobacillus ferrooxidans, Acidithiobacillus thiooxidans 和 Lepthospirillum ferrooxidans 的一种混合...
The copper loaded on the resin forms a complex with NH3 in solution under alkaline condition. The effect of alkaline dosage (AD) on the ammonia adsorption was investigated. The maximum breakthrough bed volumes were obtained when the AD was set as 0.75 mmol OH−/mL. The higher AD did not...
It is of great significance to reveal the influence of small differences in the coordination environments of metal ions in the catalytic active centers on the selectivity of products in the electrocatalytic CO2 reduction reaction (CO2RR). Here, two types of metal-organic frameworks (MOFs) based...
The effect of presence of several ions as competing ions during the adsorption process of copper, zinc, zirconium, selenium and strontium on rivermud has been studied. The effect of concentration of competing ions on their competitive efficiencies has been concluded. The competitive efficiencies of ...
Acid phosphatase activity was proved to be relatively insensitive to zinc ions, while copper, mercury and cadmium ions effectively inhibited the activity of this enzyme. 尾-N-acetylglucosaminidase activity was sensitive only to mercury ions. Lactic dehydrogenase activity remained unaffected by heavy ...
Toxicity, growth and accumulation relationships of copper, lead and zinc in the grey mangrove Avicennia marina (Forsk.) Vierh. The effects of three heavy metals Copper (Cu), lead (Pb) and zinc (Zn), and the interaction of an essential (Zn) and non-essential (Pb) metal on germinatio....
