Abstract: The problem to accelerate the transfer of UO22+ in cationic exchange resin with macro-pore was studied by analysing the elution chromatography.The accelerate, effect exerted by eight sorts of cationic ions: Ca2+, Mg2+,Mn2+,Co2+,Zn2+, Sc3+, Y3+ and La3+ and hydroxycarboxylic acid, dibasiccarboxylic acid and amino-aeid.was Studied and compared.It can be drawn that the parameter, τ, of material trasfer of UO22+ decreases with the increase of the radius of the cationic ions existed in the exchange resin.Sc3+ is an exception which is explanative.The apparent accelerate effect exerted by the dibasiccarboxylic acid was discovered and is ascribed to the formation of a neutral complex compound.
