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。
In this paper, we study the common coexisting ions, the acidity of FAAS determination of trace strontium interference. The use of 0-1% sulfosalicylic acid as a matrix modifier can eliminate or reduce these disturbances due to the fact that sulfosalicylic acid not only has the ability to complex with metal ions, but also has a dispersing and releasing agent in solution Role.
