Evaluation of DGT and DGT-PROFS modeling approach to estimate desorption kinetics of Cs in soils

The aim of this paper is to assess the suitability DGT extract kinetic rates desorption cesium (Cs) from soils. For purpose, laboratory experiments with a natural soil spiked Cs were carried out under three different contamination conditions, reflecting either an increase in level or ageing within soil. experimental results, i.e. accumulation kinetics onto probes interpreted by DGT-PROFS model. latter calculates partitioning between two particulate pools, describing weak and strong interactions respectively, as well exchange reactions. Experimental conditions did not show any major impact on rates, suggesting that significantly affected ageing. Instead, distribution among sites was shown be predominant factor governing differences observed remobilization porewater conditions. technique combined modelling approach proved efficient estimating
