The chemical behavior of TcCl62− in HCl solutions of different concentrations has been investigated. It was confirmed that TcCl62− is sensitive to ultraviolet and visual light, giving a series of aquated species the quantities of which depend on the HCl concentration. Those technetium(IV) chlorocomplexes were isolated by means of ion-exchange and paper electro-phoresis, and the composition of each species was determined by measuring the Cl/Tc ratio and the charge per species. The absorption spectra of isolated species were also measured.
