油酸钠（NaOL）是一种重要的表面活性剂，用于泡沫浮选分离氧化物矿物。NaOL在矿物表面的吸附量和吸附机理对了解浮选行为具有重要意义。本研究建立了一种简单、无毒、快速的高效液相色谱法定量分析油酸钠残留量的方法。通过与标准油酸的比较，在色谱图中鉴定了NaOL。在10 - 100 mg/l范围内观察到线性范围，并评价了精密度、准确度、LOD和LOQ。
Sodium oleate (NaOL) is an important surfactant chemical used in the separation of oxide minerals by the froth flotation process. The adsorption capacity and the adsorption mechanism of NaOL on the mineral surface are important for understanding flotation behaviour. In this study, a simple, nontoxic and rapid quantitative analysis method of High Performance Liquid Chromatography (HPLC) for residual sodium oleate concentration was proposed and verified. The NaOL was identified in chromatogram by comparison with standard oleic acid. A linear range from 10 to 100 mg/l was observed, and the precision, accuracy, LOD and LOQ were evaluated.
