Abstract
A release model for diffusion-controlled monolithic matrix coated with outer membrane system is proposed and solved by using the refined double integral method. The calculated results are in satisfactory agreement with the experimental release data. The present model can be well used to describe the release process for all c(d)/c(s). values. In addition, the release effects of the monolithic matrix coated with outer membrane system are discussed theoretically.
