- 中文摘要: A Procedure is describe for the adsorption of ion-associated complex of iron(II) 3-(2-pyridyl)-5, 6-diphenyl-1, 2, 4-triazine (abbreviated as PDT) cation with tetra phenylborate (TPB) anion on microcrystalline naphthalene. A water-insoluble ion-associated complex formed with PDT and TPB is quantitatively adsorbed on microcrystalline naphthalene. The solid mixture containing the colored complex is dissolved in acetonitrile and the absorbance was measured at 553nm. The other factors such as pH, amounts of reagents and naphthalene, shaking and standing times, diverse ions are studied. The method has been applied for the determination of iron in alloys and water samples.
