Kinetics and Mechanisms of Chemical and Biological Agents Release from Biopolymeric Microcapsules

Kinetics and mechanisms of copper cations and Trichoderma viride spores release from uncoated and chitosan coated alginate microcapsules were investigated. The gelation of a fixed amount of sodium alginate at different concentrations of copper ion solutions resulted in distinct kinetics and release mechanisms. The increase in copper cation concentration promoted, but the presence of the chitosan layer on microcapsule surface and increase in microcapsule size reduced the rate of active agent release. Fitting to simple Korsmeyer– Peppas empirical model revealed the underlying release mechanism (Fickian diffusion or a combination of the diffusion and erosion mechanisms) depends on copper cation concentration and presence of T. viride spores. The investigation pointed out that proper selection of formulation variables helps in designing microcapsules with the desirable release of copper ions and T. viride for plant protection and nutrition.
