The catalytic system Yb3+-NO3-(or NO2-)-NH4Cl has been studied cg early as 1975.In do polarography Yb3+ can be detooted as low as 5×10-5 M under optimal condition, and a linear relationship holds between the wave heights and the concentrations of 1×10-7-1×10-6 M Yb3+.The method has been used to determine micro amount of Yb in ores without the interference of other rare earths.
