将乳浊液进样技术应用于火焰原子发射光谱法，成功地测定了润滑油中的钙、钡。对乳化剂的选择、化学干扰的消除及空白溶液的配制进行了考察，提出了配制与试液粘度相同的空白溶液的原理及方法。将样品溶于本，用乳化剂ＯＰ乳化成乳浊液，然后配制成试液，喷入空气－乙炔火焰，以氯化石蜡乳浊液制成空白溶液作为参比，用工作曲线法测定。本方法的测定结果与灰化法一致，相对误差小于±３．０％，ｔ检测表明两种方法之间无显著性差异。方法灵敏、快速、准确。 The emulsion sampling technique was applied to flame atomic emission spectrometry to successfully determine calcium and barium in lubricating oil. The choice of emulsifier, elimination of chemical interference and preparation of blank solution were investigated. The principle and method of preparing blank solution with the same viscosity as that of test solution were proposed. The sample is dissolved in this, with emulsifier OP emulsified into emulsion, and then formulated into a test solution, spray into the air - acetylene flame, chlorinated paraffin emulsion made blank solution as a reference, using the working curve method. The method of determination of the same ashing method, the relative error less than ± 3.0%, t test showed no significant difference between the two methods. The method is sensitive, fast and accurate.
