A Study on the Kinetics of the Europium Electrochemistry Reduction 1.The Polarization Properties of Europium Reduced at the Cathode

摘要

This article studies the polarization properties of the cathode reduction of Eu in the Sm-Eu-Gdchloride system by using a constant potential method.As the feed concentration,temperature,and stirringrate of the system change,the system can gradually turn from chemical polarization to concentrationpolarization,and there would be a higher limiting current.As to the effects of acidity,only at a rather higherpH there will be a typical polarization property.The study can give some bases for the Eu electroreductiontechnlolgy parameter selection.
