Radiocarbon Sorption on Loess and Improved Loess Samples

Abstract:

14C sorption characteristics on the natural loess sampled from Saligny site and on mixtures of loess with different percents of Portland cement and Na type bentonite were determined performing batch sorption experiments. These experiments showed that while the bentonite added to the natural loess has a negligible effect on 14C sorption, the low 14C distribution coefficient on the natural loess is considerably improved by the Portland cement added to the loess. The values of 14C distribution coefficient increased from 2.06L/Kg for natural loess to 42.40 L/kg by adding 9% of cement to the natural loess. This could have an important effect on the radiological impact due to the 14C waste disposal on Saligny site.
