| Popis: | The technology of obtaining graphene-based materials via graphite intercalation involves dissolution of solid ammonium persulfate granules in sulfuric acid. The objective of mathematical modeling of the process of synthesizing such materials is to develop a methodology for calculating parameters of industrial equipment. In this regard, an interval algorithm for simulating processes with moving interface boundaries is used herein. Mathematical models were presented for the dissolution of solid ammonium persulfate granules in sulfuric acid during and without mixing. The conditions of the mass transfer from the granule surface were considered in both cases. The developed mathematical models make it possible to assess the dissolution kinetics and the time for complete granules dissolution depending on the conditions of the process and the conditions ensuring its completion within a specified time frame. |
