✦ Synopsis

The smgle-sweep polarographlc behavlour of Eu(III)-TTHA (tnethylenetetraammehexaacetic acid) complex was studied In 0 1 mol 1-l NH&l + 0 1 mol I-' NH, solution, the electrode reactlon of the complex LS [Eu(III)L13-+ e + ENI) + L6-and the polarograplnc current IS controlled by the diffusion process of the complex The method can be used to determme trace Eu concentrations In the range 2 5 x 10e6-5 0 x 10e4 mol I-' m solution
