The efficient separation of palladium, one of the precious metals, is one of the most challenging works that have not been solved. Based on soft-ligand multi-nitrogen organic agents, a new triazine-containing hybrid functional silica-adsorbent, BisDiOTP@SiO2, was prepared and characterized. The uptake of more than ten representative metals towards BisDiOTP@SiO2 was investigated in the wide range of 0.4-5.0 M HNO3. The high uptake ability and excellent selectivity of Pd(II) towards BisDiOTP@SiO2 were indicated. The enrichment and removal of Pd(II) by batch experiments through six cycles of uptake and desorption were conducted. The separation efficiency was 99.3% for Pd(II), 5.9% for Co(II) and less than 0.2% for all others. Pd(II) was separated effectively from others. A new technical process entitled SPMP (Simultaneous Partitioning of MA(III)/Pd(H) by Extraction Chromatography) for Pall) separation along with minor actinides has been developed.
