“…22,23 Most of spectrophotometric methods for the Iridium determination are not enough sensi-tive, selective and need heating or extraction. 1,2,4,11,[24][25][26][27] For this reasons the goal of our research was to find the effective analytical reagents for spectrophotometric Ir(IV) determination using azolidones derivatives. One of them was a new reagent -5-[2-(4-hydroxyphenyl)hydrazineylidene]-4-iminothiazolidin-2-one (HPIT).…”

The paper presents a new azolidone derivative-5-[2-(4-hydroxyphenyl)hydrazineylidene]-4-iminothiazolidin-2-one (HPIT) studies and its interaction results with iridium(IV) ions. The Ir(IV) with this reagent in the pH = 5.0 without heating forms a stable complex (λ max = 328 nm). The stoichiometric ratio of Ir(IV) to the reagent in complex is 1:1. The molar absorptivity and Sandell's sensitivity are 5.57 × 10 3 L mol-1 cm-1 and 0.034 µg cm-2 respectively. The calibration curve is linear in the range of 1.0-11.5 µg mL-1 of Ir(IV) (R = 0.9996). The limit of detection is 0.4 µg mL-1. Based on the conducted investigation a rapid and simple, spectrophotometric method for the determination of Ir(IV) using 5-[2-(4-hydroxyphenyl)hydrazineylidene]-4-iminothiazolidin-2-one as a chromophoric reagent was developed. The iridium(IV) was determined in various synthetic mixtures and alloys.
