摘要：A novel potassium nickel hexacyanoferrate (KNiHCF) sorbent-encapsulated polymeric beads (SEPBs)were synthesized by phase inversion method, characterized by various techniques viz. FTIR, optical microscopy, SEMand TGA, and used for extraction of cesium. Polyether sulfone was used to encapsulate the KNiHCF sorbent. Thebatch extraction method was used, to study the effect of different physical parameters on the extraction process. Thekinetics measurement suggests about 200 min equilibration time was sufficient to extract maximum amount of cesiumfrom solution. Various kinetic and isotherm models were used for analysis of the extraction data, which is found to fitwell in the pseudo-second-order model and the Langmuir isotherm model. The experimental maximum sorptioncapacity was found to be ~22.5 mg/g which is very close to the theoretical monolayer capacity ~ 23.1 mg/g for the drySEPBs.
