傅里叶红外光谱分析和俄歇电子能谱研究揭示,疏基乙酸钠呈化学吸附固着在黄铜矿表面,其吸附层特性与接触时间等因素有关。吸附有Cu(SCH_2COO)_3~-的黄铜矿表面亲水,巯基乙酸钠几乎与辉钼矿不作用,故可用来浮选分离铜钼矿石。 Fourier transform infrared spectroscopy and Auger electron spectroscopy study revealed that sodium thiosulfate was chemisorbed on the surface of chalcopyrite. The characteristics of the adsorbed layer were related to the contact time and other factors. Chalcopyrite adsorbed on Cu (SCH_2COO) _3 ~ - is hydrophilic, and sodium thioglycollate has almost no effect on molybdenite, so it can be used for flotation separation of copper and molybdenum ore.
