Evaluation of polymer inclusion membranes containing calix[4]-bis-2,3-naptho-crown-6 for Cs recovery from acidic feeds: Transport behavior, morphology and modeling studies

► Transport of Cs across PIM containing CNC was investigated. ► Significant Cs transport was seen with NPOE and TBP as the plasticizer. ► Transport of Cs was correlated with membrane morphology. ► Selectivity studies were found to be quite encouraging. ► A mathematical model was developed to simulate the transport process.
