Six different methodological features of the batch sorption experiment were investigated using 152Eu, Kivetty granite, saline water with initial pH of 8.5, 9 and 10, [Eu]tot=5*10-7M, S:L = 1:20, pre-washing of granite, occasional shaking, centrifugation,wall sorption correction with separate tubes. This gave final Rd= 8.3±2.1, 7.3±2.6 and 8.6±3.7m3/kg at 6 months for each pH, respectively. Then [Eu]tot and S:L were varied, filtration was compared with centrifugation, separate tubes for wall sorption was compared with wall desorption, pre-washing of granite was compared with no washing and two shaking methods werecompared. Two of the investigated methodological features gave too large apparent Rd due to: 1) filter sorption, and 2) low radiotracer concentration, leading to detection problems.
