On November 30, 2012, Ye, Yanq-Qing; Yang, Xin-Zhou; Li, Xeu-Sen; Yao, Fu-Quan; Hu, Qiu-Fen published an article.Electric Literature of 51566-22-4 The title of the article was Study on solid-phase extraction and graphite furnace atomic absorption spectrometer (GF-AAS) for the determination of platinum, palladium, and gold. And the article contained the following:
A new sorbent was prepared by immobilization of 3-methyl-2,6-diaminopyridine (MDMP) on MCI-GEL resin and then used as a solid phase extraction sorbent for trace Pt, Pd, and Au ions. The parameter for solid phase extraction (effects of pH, the sample flow rate and volume, the elution condition, and the potentially interfering ions) were carefully investigated. In the desorbed medium, Pt, Pd, and Au were determination by graphite furnace at. absorption spectrometer (GFAAS). The effect on the at. signal was eliminated by selecting proper pyrolysis and atomization temperatures for all analysts. This method was applied to the determination of trace Pt, Pd, and Au in the geol. samples. The RSDs were 3.6-4.8 %. The standard recoveries (three different concentrations of markers: 0.02, 0.04, and 0.08 μg) ranged from 92-107 %. The results were satisfactory. The experimental process involved the reaction of 3-Methylpyridine-2,6-diamine(cas: 51566-22-4).Electric Literature of 51566-22-4
