High-capacity and selective ammonium removal from water using sodium cobalt hexacyanoferrate.

ABSTRACT: A new NH₄ ⁺ adsorbent with high capacity and selectivity, sodium cobalt(ii) hexacyanoferrate(ii) (NaCoHCF, Na _y Co(ii) [Fe²⁺(CN)₆] _x ·zH₂O), was prepared. The adsorption performance was investigated by varying the mixing ratio of [Fe(CN)₆]^4- to Co²⁺ during synthesis, R _mix. The ammonia capacity was found to be proportional to R _mix, indicating that the NH₄ ⁺ capacity can be increased by increasing the Na⁺-ion content in NaCoHCF. To conduct a detailed study, we prepared homogeneous nanoparticles by flow synthesis using a micromixer with R _mix = 1.00. Even on the addition of a
