摘要

A model chlorpyrifos microcapsule was prepared using coordination assembly between Fe3+ and tannic acid (TA). The influence of independent variables such as the dropping rate of TA (X-1) and Fe3+ (X-3), the concentration of TA (X-2) and Fe3+ (X-4), and the reaction temperature (X-5) on the encapsulation efficiency (R-1) and release characteristics (R-2) of the microcapsule had been investigated, based on a central composite design with five factors and five levels. The results showed that the main factors influencing R-1 and R-2 were X-4 and X-2, then the interaction between X-2 and X-4, followed by X-5 and X-3. The optimal formula mainly based on higher R-1 and lower R-2 were determined and then tested. The optimized conditions led to an encapsulation efficiency and cumulative release proportion of 97.12%+/- 0.72% and 40.07%+/- 0.53%, along with the average relative errors of predicted values being 1.78% and -1.60%, respectively.
