Extraction of Iridium(IV) by 1-(2-(2,4-Dichiorophenyl)-4-propyl-1,3-dioxolan-2-yl-methyl)-1H-1,2,4-triazoIe from Hydrochloric Solutions

摘要

Extraction of iridium(IV) by 1-(2-(2,4-dichlorophenyl)-4-propyl-1,3-dioxolan-2-yl-methyl) ~1H 1,2,4-triazole from hydrochloric solutions was studied. Optimal extraction parameters were determined. The mechanism of iridium(IV) extraction in this system is ion exchange (3.0 mol/L HC1 and tau_(cont) = 5 min). Electronic,~1H NMR, ~(13)C NMR, and IR spectroscopy and elemental analysis were used to determine the composition of the extracted compound.
