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 flameThe absorption signal of strontium was increased by 50% in the presence of sulfosalicylic acidAt the same time it can reduce and eliminate the interference of foreign ionsThe determination of strontium by micro-sampling flame atomic absorption spectrometry with 0.5% sulfosalicylic acid as a matrix modifier was proposedThe method can be applied to the determination of strontium in wild cabbage with the satisfactory result.
