15A novel biosorbent derived from agricultural residue -walnut shell (WS) is reported to remove cesium from aqueous 16 solution. Nickel hexacyanoferrate (NiHCF) was incorporated into this biosorbent, serving as a high selectivity trap 17 agent for cesium. Field emission scanning electron microscope (FE-SEM) and thermogravimetric and differential 18 thermal analysis (TG-DTA) were utilized for the evaluation of the developed biosorbent. Determination of kinetic 19 parameters for adsorption was carried out using pseudo first-order, pseudo second-order kinetic models and 20 intra-particle diffusion models. Adsorption equilibrium was examined using Langmuir, Freundlich and
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
