Use of mathematical modeling for a comparative assessment of the sorption properties of natural and synthetic zeolites to cobalt
Comparison of the sorption capacity of natural zeolite (clinoptilolite) and synthetic zeolites (NaX and NaA) in relation to cobalt ions is done under dynamic conditions. The sorption capacity of zeolites in relation to cobalt was: for clinoptilolite - 59.00 mg/g; for zeolite NaX - 87.03 mg/g; for ze...

| Summary: | Comparison of the sorption capacity of natural zeolite (clinoptilolite) and synthetic zeolites (NaX and NaA) in relation to cobalt ions is done under dynamic conditions. The sorption capacity of zeolites in relation to cobalt was: for clinoptilolite - 59.00 mg/g; for zeolite NaX - 87.03 mg/g; for zeolite NaA - 73.00 mg/g. Based on the data obtained, mathematical modeling of sorption isotherms was carried out using the Langmuir equation, Chebyshev criterion, and the criterion of the least-squares method. The performed correlation of the factual and model results indicates that the considered models adequately reflect the sorption processes taking place in zeolites. The results obtained make it possible to use the considered models for prognostication of the behavior of zeolites with respect to cobalt. |
