Abstract
The thermochromatographic behavior of berkelium chlorides in various chlorinating gases was studied. Using Cl2 or a mixture of Cl2/SOCl2, two peaks were observed in a thermochromatographic column. The "high temperature" peak corresponds to BkCl3 and the "low temperature" one corresponds most probably to BkCl4. Using both the model of mobile adsorption and the of Monte Carlo method, the adsorption enthalpies were determined. The possible chemical reactions in a chromatographic column are discussed.
