A Highly Efficient Adsorbent Cu-Perusian Blue@Nanodiamond for Cesium in Diluted Artificial Seawater and Soil-Treated Wastewater.

ABSTRACT: A new adsorbent Cu-Perussian blue@Nanodiamond (Cu-PB@DND) for Cs⁺ removal was prepared and characterized with IR, SEM, X-ray diffraction, particle size analysis, and zeta-potential. The adsorbent consists of a core of aggregated detonation nanodiamond (DND) particles with the surface treated with Cu-PB. Cesium adsorption was studied in two modes; a co-precipitation mode and a batch mode. In the co-precipitation mode, DND, CuCl₂, and K₄[Fe(CN)₆] were added sequentially to a Cs⁺ solution in diluted artificial seawater. In the batch mode, adsorbent Cu-PB@DND was dispersed into a Cs⁺ solution with stirring. The distribution coefficient (K_d) of the co-precipitation mode was 8.8 × 10⁷ (mL/g) at Cs⁺
