摘要
本文研究了常见共存离子、酸度对ＦＡＡＳ测定微量锶的干扰。用０－１ ％ 磺基水扬酸作基体改进剂可以消除或降低这些干扰，其原因，不仅是磺基水扬酸具有与金属离子配合的能力，而且它在溶液中具有分散作用和释放剂的作用。
The present paper covers the influence of foreignions and pH on absorption signal of strontium by FAAS. It can eliminate or reduce the interference with 0.1 % sulfosalicylic acid as a matrix modifier. The effectiveness of sulfosalicylic acid in eliminating the interference arises out of its coordination and serve as dispersion and release in solution.
