目前测定尿铅的标准方法是WS/T 18-1996《尿中铅的石墨炉原子吸收光谱测定方法》[1],普遍认为使用基体改进剂对于改善石墨炉原子吸收光谱法测定生物样品中铅具有很大的作用。本文用Triton X-100稀释尿样,使用氯化钯作为基体改进剂标准曲线法直接进样进行测定。表面活性剂Triton X-100稀
The current standard method for the determination of urinary lead is WS / T 18-1996 “Graphite Furnace Atomic Absorption Spectrometry for the Determination of Lead in Urine” [1]. It is generally accepted that the use of matrix modifiers to improve the determination of lead in biological samples by graphite furnace atomic absorption spectrometry Has a great role. In this paper, Triton X-100 diluted urine samples using palladium chloride as a matrix modifier standard curve method for direct injection was measured. Surfactant Triton X-100 dilute
