Results on cesium extraction by calixarene crown-ether in several diluents are presented. An extraction mechanism was proposed, which correctly fits the different datasets. Found empirical equilibrium constants were correlated with diluent parameters for a better comparison. Afterwards, chloroform and 2-nonanone were compared on the obtained distribution ratios, separation factors and atomic scale differences. EXAFS studies proved that the modification of diluent yields a change in the local cesium environment.
