The equilibrium parameters of the extraction of iodine from aqueous model solutions of various compositions have been determined and the infl uence of the background mineralization of the raffi nate has been revealed. The eff ect of the isooctane/tributylphosphate (TBP) ratio on the extraction of iodine from aqueous solutions with diff erent ionic strengths has been determined by the isomolar series method. The hypothetical composition of hydrate-solvate complexes has been established both experimentally and using computer modeling tools.
