Summary  

In a previous paper we studied the interaction of the radionuclides 110mAg, 60Co and 65Zn with peat humin. These nuclides are among the fission or corrosion products in nuclear reactors. The aim of this paper is to study the effect of certain ligands, which are present in the environment, such as humic acid, fulvic acid, EDTA and urea, on the sorption of these radionuclides by humin. The obtained results indicated that urea has no effect on the sorption of Co and Zn by humin, and only a little in case of Ag. However, the presence of the other ligands (humic acid, fulvic acid or EDTA) leads to different decreases in the sorption of the three nuclides by humin. The results are interpreted in the light of the complex formation between ligands and the metal cations and of the strength of binding of these cations to the humin sorbent. The release of Ag+in the presence of different ligands was found to follow the order: humic acid>EDTA>fulvic acid>urea. In the case of both Co2+and Zn2+, the sequence is changed to be: EDTA>humic acid>fulvic acid>urea, with a higher release in the case of Zn2+. The results showed that cobalt is bound more strongly to humin than silver and zinc. The sulphur content of the humic fractions plays a significant role in the competition for silver and zinc.
