Recovery of copper and tin from stripping tin solution by electrodepositionBin Li1,De-An Pan1,Yu-Hui Jiang1,Jian-Jun Tian1,Shen-Gen Zhang1,Kun Zhang21. Institute for Advanced Materials and Technology...">In this paper, the method of recycling copper and tin by constant-current and constant-voltage electrolysis from the stripping tin solution of tinned copper wastes was studied. The experimental......
Solvent extraction and stripping of lithium ion from aqueous solution and its application to seawaterGregorius Rionugroho Harvianto,Seok-Hyeon Kim,Chang-Sik JuDepartment of Chemical Engineering... parameter. After extraction, lithium ion could be easily stripped from the extraction solution by acidic solutions. Stripping efficiency decreases with p H of acidic solutions, and the kind of acid does......
in the solution of stripping the nickel coating on NdFeB permanent magnet on the stripping result were studied systematically.The practical formular contains mainly the oxidant m-O2NC6H4SO3Na, the complex...Study of Technology of Stripping Nickel Coating on NdFeB Permanent Magnet Rao Houzeng1,Jiang Longfa1,LI Guohua2,Lin Guanjie1 (1.Department of Environmental and Chemical Engineering, Nanchang......
stripping method of titanium alloy oxide films was studied. An environment friendly solution hydrogen peroxide and sodium hydroxide without hydrofluoric acid or fluoride were used to strip the oxide films... of the oxide film was in the range of 5-6 μm. The oxide films were stripped for 2 to 8 min in the solution. Moreover, the effect of the stripping time on the efficiency of the film stripping......
stripping agents: distilled water, 0.5 mol/L HF and 1.0 mol/L HF. The results given in Table 4 showed that 0.5 mol/L HF stripped 86.7% of the loaded niobium. Two volumes of ammonia solution (33%) were...]quinazolin- 6(7H)-one dissolved in methylene chloride. It has been found that extraction efficiency of 84% was achieved by contacting equal volumes of 0.32% extractant with 4.5 mol/L sulfate solution......
sulfuric acid medium using Cyanex 923 in heptane solution was investigated. The effects of extractant concentration, pH and sulfate ion as well as stripping agents, acidity and temperature...Extraction and Stripping of Ytterbium (Ⅲ) from H2SO4 Medium by Cyanex 923 Li Hongfei1,Meng Shulan1,Li Deqian1,Wang Weiwei1,Wang Xianglan1 (1.Key Laboratory of Rare Earth Chemistry and Physics......
