Abstract

Herein, controlled-release material for atrazine (ATZ) herbicide was formulated using different ratios of kaoline (Kao) clay-loaded starch (ST)-grafted chitosan (CHT). The materials were characterized by FTIR, SEM and EDX. The ATZ-release kinetics were studied using the zero-order, first-order and Korsmeyer–Peppas models. The percentage release of the active ATZ in the ST-g-CHT/Kao/ATZ, Kao/ATZ and bare ATZ were 9, 57 and 99 within 96 h, respectively. The Korsmeyer–Peppas model better described the release of active ATZ from the ST-g-CHT/Kao/ATZ system (R² = 0.999), which delineates a non-Fickian diffusion mechanism that the release was controlled by diffusion and dissolution.
