摘要: Propericiazine (PPC) is proposed as a new sensitive and selective reagent for the spectrophotometric determination of microgram amounts osmium. PPC forms an orange-red colored species with osmium(VIII) or osmium(VI) instantaneously at room temperature in 6 M hydrochloric acid medium. The exhibits maximum absorbance 511 nm. Beer′s law valid over concentration range 0.1–8.0 ppm 0.20–10 osmium(VI). Sandell’s sensitivity reaction 9.4 ng/cm2 13.5 effects time, temperature, acidity, order addition reagents, diverse ions are investigated. application method osmium content synthetic syserkite mineral has been explored.
