Original Abstract

The aim of this work was the study of relation between chemical and thermal stability of complexes of humic acids with heavy metals (nickel, cobalt and copper). Complexes were prepared with metal solutions of three different initial concentrations. Chemical stability was determined as an amount of releasedmetal ions, two of extraction agents were used (solution of MgCl2 and HCl), total boundedamount was distribute into three different fractions; residual fraction, strongly bound fractionand mobile and ion-exchangeable fraction. Changes that occured in the structure of humic acidsafter complexation and extraction were investigated by FT-IR spectrometry. Thermo-oxidative stability was tested by means of thermal analysis.
