Preparation of new class composite adsorbent for enhanced palladium(II) detection and recovery

Awual, M. R.; Hasan, M. M.*; Naushad, M.*; Shiwaku, Hideaki   ; Yaita, Tsuyoshi

In this study, we have developed S and N containing ligand of 5-tert-butyl-2-hydroxybenzaldehyde thiosemicarbazone. The organic ligand was anchored onto the mesoporous silica by an indirect method for the preparation of composite adsorbent. The adsorbent can detect Pd(II) ions at ultra-trace levels and recover the Pd(II) with high sorption capacity and efficiency. The adsorption isotherm data were well fitted with the Langmuir model, and the maximum sorption capacity of the composite adsorbent was 171.65 mg/g, which was close to the equilibrium sorption capacity.
