在克山病病因研究中,要求测定患者血液中钡和锶的含量,并希望血液用量要少。 Deloes等会用溶剂萃取人血,以原子吸收光谱法测定了十一种金属元素的含量,其中仅包括鍶。本工作使用PMBP-TBP-二甲苯体系作萃取剂,研究了萃取分离的适宜条件,拟订了一个简便而快速的操作手续,可以将血液中的硷士金属与铁、钾、钠等大量共存元素定量分离出来。最后用钽舟无焰原子吸收光谱法进符钡、鍶的测定。并详细地研究了钽
In the etiology study of Keshan disease, it is required to determine the content of sputum and sputum in the patient’s blood and hope that the amount of blood is less. Deloes et al. extracted human blood with solvents and determined the contents of eleven metal elements by atomic absorption spectrometry, including only thorium. This work uses the PMBP-TBP-xylene system as an extractant, studies the appropriate conditions for extraction and separation, and formulates a simple and fast operating procedure that can coexist large amounts of metals in the blood with iron, potassium, and sodium. Separated quantitatively. Finally, the flameless atomic absorption spectrometry method was used to determine the enthalpy and enthalpy. And studied in detail
