摘要
Abstract
The electrochemical behavior of uranylnitrate in 1-butyl-3-methylimidazolium chloride ([BMIM]Cl) has been investigated by cyclicvoltammetry and chronopotentiometry.Reduction of UO2+2 in [BMIM]Cl takes place through a single step two-electron transfer to UO2, which is reversible reaction at the potential sweep range of 10-100 mV/s. Diffusion coefficient and the energy of activation of UO(2+)2 is 9.01 × 10-8 cm2/s at 353 K and 54.6 kJ/mol, respectively. Controlled current electrolysis of a solution of uranyl nitrate in [BMIM]Cl is carried out on a stainless steel plate at 150 μA for 18 h. Uranium is successfully deposited all over the surface of a stainless steel plate.关键词
