Research on the treatment of liquid waste containing cesium by an adsorption–microfiltration process with potassium zinc hexacyanoferrate

Reverse osmosis concentrate treatment by a PAC countercurrent four-stage adsorption/MF hybrid process

“…It was found that the Freundlich model was suitable to describe the data obtained from adsorption isotherm experiments. Similar results were reported in many papers [26,27]. Eq.…”

Synthesis and characterization of magnetic hexacyanoferrate (II) polymeric nanocomposite for separation of cesium from radioactive waste solutions

“…The real challenge for solid phase separation is to select the most promising types of adsorbent, mainly in terms of high capacity and adsorption rate, high selectivity, and low cost. Many studies had presented transition metal hexacyanoferrates as promising candidates for separation of radioactive cesium from nuclear wastes over a wide pH range even in the presence of high salt loadings [11][12][13]. Recent studies have reported their potentiality for therapy of animals and humans affected by nuclear accidents [14].…”

Rapid quantification of radiocesium dissolved in water by using nonwoven fabric cartridge filters impregnated with potassium zinc ferrocyanide

“…Among the ferrocyanide compounds, potassium zinc ferrocyanide is a sorbent that can absorb alkali-metal ions, including the cesium ion, by ion-exchange with K + within its crystal structure [15][16][17][18]; it is also known to maintain a high absorption ability of dissolved radiocesium over a wide range of pH values [19]. Here, the authors attempted to improve the efficiency of absorption of radiocesium dissolved in water by developing and testing a cartridge filter incorporating a nonwoven fabric impregnated with potassium zinc ferrocyanide.…”
