- •
Potassium nickel hexacyanoferrate (PNHF) has been developed to adsorb Cs-137 in waste solution.
- •
The adsorption sequence of Cs-137 in ash solution was PNHF, Prussian blue, NaTPB, and zeolite.
- •
The adsorption sequence of Cs-137 in soil solution was PNHF, NaTPB, Prussian blue, and zeolite.
- •
The optimum injection rate of the PNHF agent to adsorb Cs-137 in waste solutions was 100 mg/100 mL.
- •
The optimum pH in the ash and soil waste solutions to adsorb Cs-137 with the agent was 7.
