he reversed-phase paper chromatography with di-isoamyl methylphosphonate(DAMP) as the stationary phase and solutions of various concentrations of nitric acid,hydrochloric acid,perchloric acid and sodium nitrate as the efliuent were investigated,The Rt values of UO2+2,Th and many radio-nnolides on paper treated with 0.1M DAMP in benzene were obtained.According to the Rt values and selecting the suitable mobile phase,good results were obtained for the separation of UO2+2-Th,90Sr-90Y,95Zr-95Nb,210Pb-210Bi-210Po and the mixture of UO2+2,Th and some radio-nuclides.The noticeably different Rt values between macro-concentration and trace level of some heavy metal ions were revealed.
