| 摘 要： | 本文研究了10种表面活性剂对乙炔空气火焰中Sr原子吸收信号的影响。磺基水杨酸能使Sr原子吸收信号增强50％,同时还有降低和消除常见的共存离子干扰的效果。采用微量进样火焰法,以0.5％(W/V)磺基水杨酸为基体改进剂测定了苷蓝中痕量锶,测定值与推荐值相符合。

| Abstract: | The present paper covers the influence of ten types of surfactants on absorption signal of strontium in acetylene air flame. The absorption signal of strontium was increased by 50% in the presence of sulfosalicylic acid. At the same time it can reduce and eliminate the interference of foreign ions. The determination of strontium by micro-sampling flame atomic absorption spectrometry with 0. 5% sulfosalicylic acid as a matrix modifier was proposed. The method can be applied to the determination of strontium in wild cabbage with the satisfactory result. |
