摘要

Nickel hexacyanoferrate (NiHCF) serves as a cathode material capable of adsorbing ammonium ions from sodium-rich solutions. Through a three-step adsorption process, NiHCF demonstrated a reduction in ammonium ion concentration from 200 to 17 mmol/L, demonstrating its efficacy in ammonium recovery and water purification within the framework of nitrogen circular technology.
