The sorption of radiocesium (137Cs) in sediments sampled from Lake Pamvotis of Ioannina was studied in a laboratory simulation. In a series of experiments, the kinetics of 137Cs sorption and 137Cs distribution profiles in sediment cores were investigated. The results have shown that a significant percentage of 137Cs (35%) is adsorbed in the sediments during the first 3 d, at a rate of 0.41 +/- 0.05 d-1. The rest of 137Cs is adsorbed with the slower rate of 0.024 +/- 0.004 d-1. 137Cs rapidly reaches (< 5 d) a depth that does not exceed 3.5 cm. The sorption of 137Cs was found to follow Freundlich's empirical law, which describes the adsorption of most substances in solution to solids.
在实验室模拟中研究了从约阿尼纳的潘沃蒂斯湖采集的沉积物中放射性铯（¹³⁷Cs）的吸附情况。在一系列实验中，研究了¹³⁷Cs吸附动力学以及沉积物岩心中¹³⁷Cs的分布剖面。结果表明，在最初3天内，相当比例（35%）的¹³⁷Cs以0.41±0.05 d⁻¹的速率吸附在沉积物中。其余的¹³⁷Cs以0.024±0.004 d⁻¹的较慢速率吸附。¹³⁷Cs在不到5天的时间内迅速达到不超过3.5厘米的深度。发现¹³⁷Cs的吸附遵循弗伦德利希经验定律，该定律描述了溶液中大多数物质对固体的吸附。
