Radioactive cesium removal from ash-washing solution with high pH and high K+-concentration using potassium zinc hexacyanoferrate

- K2Zn3[Fe(CN)6]2 is effective adsorbent for radioactive Cs decontamination of salty and high-pH water.
- K2Zn3[Fe(CN)6]2 decreased the radioactivity of ash-washing water less than standard criteria for public water.
- A method for the estimation of Cs adsorption rate from real ash-washing solution was established.
