摘 要：<正> The voltammetric behaviors of rare earth ions-amino acids were studied.The reduction potential of Eu3+was shifted positively and the peak separation of the cathodic and anodic peaks in cyclic voltammogram de-creased when a certain amino acid was added to Eu3+ solution.Experimental results showed that Eu3+ was re-duced by way of forming complexes with amino acids which were adsorbed on mercury electrode surface.Whenhistidine and formaldehyde existed simultaneously in the solution containing Eu3+,a well-defined reversiblecatalytic prewave of Eu3+ was obtained.Meanwhile,the reduction current of formaldehyde increased greatlywith the addition of histidine.The mechanism was studied.Several other rare earth ions and amino acids werealso studied preliminarily.
