摘要：

Square-wave voltammetric measurements of the Eu(III)-salicylate (Eu-Sal) complex in 0.55 mol l-1 NaCl at pH 5.3 were made. At various europium concentration levels (from 10(-8) to 10(-6) mol l-1) the redox process of the Eu-Sal complex is reversible, with adsorption of the reactant of the redox reaction. The detection limit with an accumulation time of 5 min at 0 V vs. Ag/AgCl was 10(-8) mol l-1 Eu(III). A maximum surface concentration GAMMA(max) = (2.31 +/- 0.46) x 10(-11) mol cm-2 was found.
