将乳浊液进样技术应用于火焰原子吸收光谱法 ,成功地测定了添加剂中的锌、铅 ,建立了测定润滑油添加剂中锌和铅的快速分析方法。对乳化剂的选择、背景吸收干扰、空白溶液的选择及检出限进行了考察。测定结果与灰化法-火焰原子吸收光谱法一致 ,相对误差小于± 2 5% ,t检验表明两种方法之间无显著性差异。相对标准偏差小于3 0 % ,锌的检出限 0 0 68mg/L、铅的检出限 0 2 7mg/L。本方法简便、快速、准确。 The technique of emulsion sampling was applied to flame atomic absorption spectrometry to successfully determine zinc and lead in additives and a rapid method for the determination of zinc and lead in lubricant additives was established. The choice of emulsifier, background interference, blank solution selection and detection limit were investigated. The results were in agreement with ashing-flame atomic absorption spectrometry with a relative error of less than ± 25%. The t test showed no significant difference between the two methods. The relative standard deviation was less than 30%, the detection limit of zinc was 0 68mg / L, and the detection limit of lead was 0 27mg / L. The method is simple, fast and accurate.
