浮选化学家长期以来都在研究半溶盐类矿物吸附羧酸盐捕收剂的机理 ,尤其是羧酸盐的吸附密度、吸附动力学、吸附形式 (化学吸附、物理吸附 )、定向以及构型。因为这种现象对矿物表面疏水状态的确定很重要 ,所以进行就地表面光谱研究当然是合理的。而就地测量通常是难以进行的。然而 ,2 0世纪 80年代后期开始 ,研究出了傅里叶变换红外光谱技术(FTIR) ,它可以获得在半溶盐浮选体系中许多羧酸盐吸附的详细信息。本文对单晶内反射元件的内反射光谱法用于半溶盐浮选体系中的相关情况进行了评述
Flotation chemists have long been studying the mechanism by which semi-soluble salt minerals adsorb carboxylate collectors, especially the adsorption density, adsorption kinetics, adsorption forms (chemisorption, physical adsorption), orientation and structure of carboxylates type. Because this phenomenon is important for the determination of the hydrophobic state of the mineral surface, it is certainly reasonable to perform in-situ surface spectroscopy. In situ measurements are often difficult to do. However, since the late 1980s, Fourier Transform Infrared Spectroscopy (FTIR) has been developed that provides detailed information on the many carboxylate sorptions in semi-dissolved salt flotation systems. In this paper, the internal reflection spectroscopy single crystal internal reflection element for semi-dissolved salt flotation system were reviewed
