| Abstract: | 4-(2,6-Diamino-4-pyrimidylazo)phenol (DAPP) interacts with copper(II), silver(I), and palladium(II) to give 1:2 violet, 1:1 violet and 1:1 green complexes respectively. The Sandell's sensitivity of the colour reaction is 1.1 ng cm-2 at 535 nm for copper(II), 3.1 ng cm-2 at 550 nm for silver(I) and 5.8 ng cm-2 at 625 nm for palladium(II). Other optical constants have been evaluated. Effect of foreign ions in the determination of the three metal ions has also been studied. |
