| 摘 要： | 本文叙述了用原子吸收法测定同一个少量血清样品中的无机磷和钙。血清用高氨酸沉淀蛋白后,加过量钼酸铵。在pH0.4～1.6范围内,用乙酸丁酯萃取生成的微量磷钼酸,与过量的钼酸铵分离。水相测钙,有机相用稀氨水反萃后测钼,间接分析磷。

| Abstract: | In this paper a method is described for determination of inorganic phosphate and calciumin small samples of blood serum by flame atomic absorption spectrometry(FAAS). After separa-ting protein with perchloric acid: add excess ammoninm molybdate to the sample solution, thenat pH 0.4 to 1.6 the phosphomolybdate is extracted into n-butye acetate. The aqueous phase isused for calcium determination the organic phase in stripped liquid with ammonium bydroxideand the molybdenum in stripped liquid is determined for indirect determination of inorganicphosphate. |
