石墨炉原子吸收中,铈、镨、钕基体背景吸收的研究

THE STUDIED OF THE BACKGROUND ABSORPTION OF CERIUM PRASEODYMIUM AND NEODYMIUM MATRIX IN THE GRAPHITE FURNACE AAS

本文研究了石墨炉原子吸收中铈、镨、钕氯化物和硝酸盐基体背景吸收的法长特性,时间特性和原子化条件对背景吸收的影响,并探讨了有关的机理及背景吸收来源及其消除办法。

In this paper the wavelength and time character of the background absorption of the Ce, Pr and Nd chlorides and nitrates matrix and influence, which was generated by the atomization condition, have been studied in the graphite furnace atmomic absorption and the related mechanism, background source and eliminating method were given.
