Abstract

Results of cadmium sorption and desorption, as well as distribution coefficients of cadmium in the soils from the Danubian Lowland and from Veľký Ďur (neighbourhood of the nuclear power plant Jaslovske Bohunice) are presented in this study. It was found that Cd adsorption is high in studied soils already after the one-minute lasting Cd-soil contact. The results obtained show that the highest sorption of cadmium is in the loamy-sand soil from Kalinkovo (99.75 %). Zeolite application was the most effective in the loam soil from Macov. Sorption of cadmium in this soil increased by 1.45%. The presence of zeolite in chosen soil samples influenced Cd desorption, too. In loamy-sand soil from Kalinkovo cadmium desorption decreased by 50 % after zeolite application. Sorption experiments with radionuclides (85Sr and 137Cs) were conducted on brown earth from the site Velľký Ďur. The 137Cs sorption is very high in studied soil. Zeolite is more effective in the case of 85Sr. Desorption of radiostrontium decreased by 50% after zeolite application.
