“…The amount of osmium loading in the microspheres was determined by a spectrophotometric measurement of the unused osmium left in the filtrate after Os@MS was formed. Perphenazine dihydrochloride reagent was used, which formed a red‐coloured complex with osmium in a phosphoric acid medium with an absorption maximum of 528 nm 36…”

“…The tatumerisim form could occur in triazole. As a result, the band at 1286 cm -1 assigned to the (C=S) vibrations could be observed in the spectra of the ligand 24 . It is reasonable to expect deprotonation of the ligand molecules before complexation; the complete disappearance of the band due to v (S-H) in the spectra of the complexes unambiguously supports this view.…”

“…Osmium(VIII) stock solution was prepared by dissolving 1 g of osmium tetraoxide from a sealed ampule in about 100 mL of 0.2 sodium hydroxide solution and diluting to the mark in a 1-L volumetric flask with doubly distilled water. The solution was standardized iodometrically [18]. A 100 mg mL À1 working solution was prepared by diluting the stock solution and kept in refrigerator.…”
