Facile synthesis of potassium copper ferrocyanide composite particles for selective cesium removal from wastewater in the batch and continuous processes

A composite CMC–KCuFC particle adsorbent was fabricated in this study, based on the use of a CMC biopolymer cross-linked with Cu²⁺via a syringe pump device, serving as an efficient biosorbent for Cs ion removal and adsorption from wastewater.
