Effect of HNO₃ concentration on a novel silica-based adsorbent for separating Pd(II) from simulated high level liquid waste.

ABSTRACT: A new kind of silica-based (Crea + TODGA)/SiO₂-P adsorbent with high selectivity adsorption for palladium (Pd) was synthesized to examined the applicability for partitioning process of high level liquid waste (HLLW). Adsorption behavior of Pd(II) towards (Crea + TODGA)/SiO₂-P adsorbent and stability of adsorbent against HNO₃ solution were investigated by batch method. The degradation parts of (Crea + TODGA)/SiO₂-P dissolved in liquid phase were estimated by total organic carbon (TOC) analyzer. (Crea + TODGA)/SiO₂-P adsorbent showed good selectivity adsorption for Pd(II) and reached equilibrium within 24 hr. The adsorption ability of (Crea + TODGA)/SiO₂-P for Pd(II) and the content of TOC leaked decreased with the increasing
