摘要

In this paper several models of the mass transfer process are described with the aim of simulating the release of active principles from matrix-type polymeric microcapsules. The following mathematical models, which are available in the literature, are applied in this study: Fick's second law (CDMASSA), the linear drive force (LDF), an analytical model and other semi-empirical models. The release of the active principle (betacarotene) contained in microcapsules (PHBV) into a solvent (ethanol) was investigated. It was observed that the model obtained with Fick's second law provided a better fit with the literature data compared with the LDF model, the analytical model and the semi-empirical models. It can be concluded from this finding that the most complete model, based on the phenomenology of the problem, provided the best result. Highlights ? Study the suggested models and analyze what is the most appropriate for each case study. ? Evaluating prediction errors obtained through different models, using statistical tools. ? Discuss the different phenomenological approaches of experiments and models, because different parameters are involved.
