应用STPF技术测定痕量钯国内尚末见报道。J.Fazakas做了这方面的初步工作,比较了平台原子化时各分析线的灵敏度,但末涉及具体应用问题。本文采用自制改型Lvov平台施以STPF的整套技术,测定经MBT-MIBK体系萃取后的有机相的钯。在优化后的分析条件下,各种共存组分对钯的测定无显著影响,钯的灵敏度为29.5pg/0.0044A.S,矿样分析的精密度在2.6～7.3％之间。本法可应用于地质样品中痕量钯的测定,分析结果与推荐
The application of STPF determination of trace palladium is not yet reported in the country. J. Fazakas did preliminary work in this area, comparing the sensitivity of the analytical lines at the platform atomization, but at the end of the application-specific issues. In this paper, a homemade modified Lvov platform with STPF set of technologies, measured by the MBT-MIBK system after extraction of the organic phase of palladium. Under optimized analytical conditions, the various coexisting components had no significant effect on the determination of palladium, with a sensitivity of 29.5 pg / 0.0044 A for palladium and between 2.6 and 7.3% for mineral samples. This method can be applied to the determination of trace amount of palladium in geological samples, the analysis results and recommendations
