摘　　要：虽然有很多现代测试技术可以用来测定脂肪酸类捕收剂在氧化矿表面的吸附量,但灵敏、方便和实用的方法并不多。燃烧法测定脂肪酸类捕收剂在氧化矿表面的吸附量具有速度快,设备简单的优点,具有很强的实用性,非常适合于氧化矿浮选捕收剂的试验研究。主要对燃烧法中差热分析法、载流燃烧法和顶空气相红外分析法的发展现状与应用进行了评述。Although there are many modern analytical techniques that can be used to measure the adsorption of fatty acid collectors on oxide minerals,few are sensitive,convenient and practical enough to be used for quantative analysis of the collectors.Due to fast speed and simplicity of the instrumentation,conbustion method is very suitable for flotaion research.In this paper,the development statuses and applications of the differential thermal analysis（DTA） used in combustion method,selective oxidation combustion method and headspace analysis by gas-phase infrared spectroscopy（HAGIS） were reviewed.
