摘要:

A spectrophotmetric study of the Os(VIII) complex of a reagent 3,4-dihydro-4,4,6-t rimethy-2-(1H)-pyrimidinethione (DTPT) is presented. A violet complex Os (DTPT)4is formed in a strong acid solution which is soluble in water and shows maximum absorbance at 495 nm with molar absorptivity of 5.1×103l. mol−1.cm−1. Beer's law is obeyed up to 24 ppm of Os(VIII). Sandel's sensitivity of the reaction of Os(III) is 0.039 μg.cm−2per 0.001 absorbance unit. Hg(II), Pd(II), Ru(VIII), Cu(II) and S2-interfer
