Abstract
Polyurethane was prepared from toluene diisocyanate (TDI) and triethanolamine esters. The equilibrium and kinetic characteristics of the uranium sorption onto polyurethane were determined. The adsorption factors were optimized. The adsorption capacity for uranium reaches 70 mg/g and agrees with the value obtained by fitting with the Langmuir isotherm (75 mg/g). The adsorption process follows pseudo-second-order rate equation.
