Facile synthesis of polydopamine-interlinked titanate nanosheets and copper hexacyanoferrate for highly efficient removal of Cs(I)

A novel efficient adsorbent (TNSs@PDA@CuHCF) was synthesized by polydopamine coating and copper hexacyanoferrate loading on titanate nanosheets and applied to adsorb Cs(I) form aqueous solution. The adsorbent exhibited an excellent adsorption capacity for Cs(I) (374.53 mg/g at 298 K). Adsorption beh...

Description
Summary:A novel efficient adsorbent (TNSs@PDA@CuHCF) was synthesized by polydopamine coating and copper hexacyanoferrate loading on titanate nanosheets and applied to adsorb Cs(I) form aqueous solution. The adsorbent exhibited an excellent adsorption capacity for Cs(I) (374.53 mg/g at 298 K). Adsorption behavious of Cs(I) on TNSs@PDA@CuHCF could be well described by the Langmuir isotherm model and the pseudo-second-order kinetic model, respectively. Thermodynamic analysis revealed that adsorption of Cs(I) was a spontaneous and endothermic process. The interaction of Cs(I) and adsorbent was largely attributed to ion exchange.
