and chromium are 40.54 and 50.27 kJ/mol, respectively. Vanadium and chromium spinels are oxidized after the decomposition of fayalite and quartz phases. Key words: vanadium slag; potassium hydroxide.... [13] XIAO Qing-gui, CHEN Yin, GAO Yi-ying, XU Hong-bin, ZHANG Yi. Leaching of silica from vanadium-bearing steel slag in sodium hydroxide solution[J]. Hydrometallurgy, 2010, 104(2): 216-221. [14......
. Applied current density was controlled at 5 A/dm2. The specimens were PEO-coated in an electrolyte constituted by 0.18 mol/L potassium hydroxide, 0.09 mol/L potassium fluoride, 0.08 mol/L sodium silicate.... The thickness of oxide layer increases with increasing coating voltage. The oxide layer formed on AZ91 Mg alloy in electrolyte with potassium permanganate consists of MgO and Mn2O3. Corrosion......

136.1 文献标识码:A Separation of aluminum and silicon in clean production process for potassium dichromate WANG Shao-na1, 2, ZHENG Shi-li 1, ZHANG Yi1 (1. Institute... in the clean production process for potassium dichromate was studied. The thermodynamic calculation results indicate that there is no produce of poisonous CaCrO4 when CaO is added into solution. When......
Enhanced Cu(Ⅱ) adsorption by orange peel modified with sodium hydroxide FENG Ning-chuan(冯宁川)1, 2, GUO Xue-yi(郭学益)1, LIANG Sha(梁 莎)1 1. School of Metallurgical Science and Engineering, Central... ____________________________________________________________________________________________ Abstract: Copper adsorption by orange peel, which was chemically modified with sodium hydroxide, was investigated. The adsorbent......
Engineering, Chinese Academy of Sciences, China, has proposed a method for oxidative leaching of chromite with potassium hydroxide. Understanding the mechanism of chromite decomposition, especially in the potassium hydroxide fusion, is important for the optimization of the operating parameters of the oxidative leaching process. A traditional thermodynamic method is proposed and the thermal......
. [30] OKMAN I, KARAGZ S, TAY T, ERDEM M. Activated carbons from grape seeds by chemical activation with potassium carbonate and potassium hydroxide [J]. Applied Surface Science, 2014, 293: 138–142... cm3/g. The ten-fold enhancement of NO adsorption on K2CO3 ACs compared to the unimpregnated activated carbon was mainly attributed to the formation of potassium nitrite, which was confirmed by FTIR......
