This study aims to develop a novel sensor ensemble adsorbent for rapid sensing and recovery of Pd(II) from water. A highly selective and efficient adsorbent was prepared by immobilization of the synthesized ligand onto mesoporous silica monoliths and applied for successful detection and recovery of Pd(II) ions with high selectivity and sensitivity. The effects of various parameters such as pH, contact time, initial concentration, selectivity and sensitivity, on the detection and sorption of Pd(II) by the adsorbent were investigated. The results showed that the maximum sorption capacity was found at pH3.50 and adsorbent was selectively adsorbed Pd(II) ions from binary and multi mixtures even in the presence of various competing ions. The adsorbent was stable without significant loss of sorption and recovery performances even after several reuses cycles.
