- 中文摘要: A spectrophotometric method for the determination of trace amounts of tantalum (V) with 5-7-diiodo-8-hydroxyquinoline is described. With this reagent tantalum forms a yellowish-orange coloured complex which is stable in the pH range of 8.5-9.0. The coloured complex obeys Beer’s law over the concentration range of 1-10 μg tantalum (V) ml-1 at ai5m, in aqueous solution with a molar absorptivity of 5.305×10… l mol¯1 cm¯1. The metal: ligand ratio ML2 was confirmed by Job’s continuous variation and mole ratio methods. The method was used to determine tantalum un steals.
