摘要：
A method has been developed for the extraction chromatographic separation of barium from 0.01 M picric acid solution with dibenzo-18-crown-6 coated on hydrophobic silica gel as the stationary phase. Various mineral acids can be used as stripping agents. Barium was separated from other elements by selective extraction and the separation of barium from alkali and alkaline earth metals, uranium, thorium and lead was achieved. The method was applied to the determination of barium in real samples.
