Report
Sorption of Cs, Sr, Ce, and I by samples from the overlying rock of the Gorleben salt dome
- 1. Technische Hochschule Darmstadt (Germany, F.R.). Fachbereich 8 - Anorganische Chemie und Kernchemie im Edward-Zintl-Institut
Description
By means of shaking experiments the following data have been obtained: RS(Cs) = 0.1-230 ml/g; RS(Sr) = 0.2-4.0 ml/g; RS(Ce) = 3-130 ml/g; RS(I) = 0.05-40 ml/g. Cesium and strontium are present as ion disperse Cs+ and Sr++, and sorption mainly proceeds by ion exchange. In the groundwater pH-range between pH 5 and pH 8 the effect of colloids is observable, especially for cerium. Iodine is present as I- under anaerobic conditions, and undergoes almost no sorption (RS < 0.1 ml/g). High sorption values are attributed to the presence of organic material. (orig.)
Abstract (German)
Anhand von Schuettelversuchen werden fuer die untersuchten Proben Sorptionsbereiche mit RS(Cs) = 0,1-230 ml/g, RS(Sr) = 0,2-4,0 ml/g, RS(Ce) = 3-130 ml/g und RS(I) = 0,05-40 ml/g ermittelt. Caesium und Strontium liegen ionendispers als Cs+ und Sr++ vor, und die Sorption ist im wesentlichen auf Ionenaustausch zurueckzufuehren. Im pH-Bereich des Grundwassers zwischen pH 5 und pH 8 ist besonders fuer Cer der Einfluss von Kolloiden festzustellen. Iod liegt unter anaeroben Bedingungen in der Regel als I- vor und wird kaum sorbiert (RS < 0,1 ml/g). Hohe Sorptionswerte sind auf den Anteil an organischem Material zurueckzufuehren.
