[Research of the effect of ascorbic acid prereduced Pd in the determination of micro quantity of Mn with GFAAS].
In this article, method of determination of micro quantity of Mn with GFAAS and Pd have been researched, results of different additional methods of Pd were compared the combining energy of Pd in three heating steps were determined by X-ray Photoelectron Spectroscopy. The point was given that as a catalyst reduced Pd changed courses of Mn atomization, and when pre-reduced Pd was used because of its much larger surface area, method had much better RSD and had much stronger signal than other methods in those cases Pd was used too.
