Engineering a defect-rich Prussian blue analog composite for enhanced Cs⁺ removal performance

Abstract

A defect-rich Zn–PBA/NPC composite was engineered for the first time, and it demonstrated excellent Cs+ removal performance, with an ultrafast Cs+ adsorption rate and high adsorption capacity.

“…Moreover, the value of 1/ n in the Freundlich isotherm model was 0.4891, further suggesting the favorable adsorption of Cs + on the CBPs. 22 At the same time, the calculated maximum Cs + adsorption capacity of the CBPs was 115.06 mg g −1 , which was close to the actual equilibrium adsorption capacity and comparable to reported phosphate-containing adsorbents such as ammonium phosphomolybdate and zinc phosphate. This high adsorption capacity of Cs + for CBPs was related to its rich phosphate groups.…”
