摘要:
介绍了一种测定捕收剂-油酸钠的方法,即定容、气体循环燃烧法.实验表明：油酸钠在500 ℃充足氧气条件下燃烧,再经600 ℃催化氧化所产生的CO2与油酸钠质量间具有良好的线性对应关系,可用于油酸钠的定量分析测定；用该方法测定脂肪酸类捕收剂在矿物表面的吸附量简单、易行.
Abstract:
A combustion method with constant volume and oxygen circulation was investigated to quantitatively determine fatty acid collector adsorbed on minerals. Tests using sodium oleate showed a very good linear relationship between the amount of sodium oleate and the CO2 produced when sodium oleate was burnt at 500 ℃ and further catalyzed oxidized at 600 ℃. This means it can be used to quantitative analyze fatty acid collector adsorbed on minerals. The method was proved to be practical and easy to realize.
