Experimental study and modelling of Cs-137 sorption behaviour in the Baltic Sea and the Curonian Lagoon

Popis výsledku v původním jazyce

Sorption-desorption behaviour of Cs-137 in the Baltic Sea and the Curonian Lagoon was studied in 1997-2009 with the aim to better understand processes responsible for redistribution and sink of Cs-137 in the system. Data obtained from several sampling campaigns were analyzed and short and long-term kinetic tracer experiments using natural water and bottom sediments were carried out with particles of various sizes from 0.0002 to 0.050 mm. Association of Cs-137 with suspended particles and bottom sediments collected during two sampling campaigns was studied using sequential extraction. Data obtained from tracer kinetic sorption experiments with Cs-134 and bottom sediment fractions of different grain size were used for finding a suitable kinetic sorptionmodel, kinetic constants and the corresponding equilibrium K-d values. It has been found that the modelled data best conform to the mechanism of ion diffusion through the so-called inert layer on the surface of the sediment particles.
