Abstract

The stability constants for tracer concentrations of Co(II) complexes with the red earth fulvic acid were determined at pH 3.8-6.8 and ionic strength 0.0010-1.0 mol/l by using the cation exchange equilibrium method and the radiotracer ⁶⁰Co. The effects of ionic strength and pH on the stability constants of 1:1 Co(II) complexes were investigated, and it was found that the stability constants of complexes of humic substances do not vary with ionic strength and pH in a manner similar to that of simple complexes.
