Kinetics of the Coordination Transformation for Preparation of Nanosized ZnS in a PVA Film

Abstract

This study was focused on the pervasion process of sulfion in a PVA–Zn²⁺ complex film. A diffusion equation for this process, based on the Fick first diffusion law, is suggested, which was in good agreement with the experimental results. The diffusion constant was 9.92 × 10^?6 cm²/sec, calculated by combining the model and the experimental results.
