To improve stability of sulfur-containing amide derivative group containing adsorbent aimed at the separation of platinum group metals from high-level liquid waste emitted from spent nuclear fuel reprocessing, thiodiglycolamic acid-functionalized silica-gel, TDGAA-Si, was synthesized from 3-aminopropyl functionalized silica-gel and thiodiglycolic anhydride. Adsorption behavior and stability were investigated by batch method. The TDGAA-Si can effectively adsorb Pd(II) from HNO₃ solution, and slow uptake rate of Ru(III) and Rh(III) were improved by temperature elevation. Stability of the TDGAA-Si was considered to be higher than thiodiglycolamic acid impregnated adsorbent because no oil droplets on the liquid phase were observed after the batch adsorption experiments using the TDGAA-Si.
