Abstract:

A non-linear, parabolic type, mathematical model is presented, simulating the movement of an organophosphate insecticide, Vapona, in plasticized polyvinyl chloride (PVC). The molecular transport of diffusant in the polymer matrix and its subsequent desorption from the surface have been characterized in terms of the integral rate coefficient for diffusion and...
