Investigation of sorption mechanism of uranium by IR-spectroscopy method

Using the method of IR spectroscopy the effect of uranium superequivalent sorption from sulphate solutions on strong-base anionites after additional treatment of saturated anionite by alkali solutions at pH=7-12 has been investigated. It is shown, that, as a result of preliminary hydrolysis, alongiside with the bridge structures the uranium hydroxocomplexes are formed, which in the process of resorption get bound with additional molecules of uranyl sulphate with the formation of polynuclear uranium complexes in the ionite phase
