Release-slowing mechanism of anisole desorption on glucose-based porous carbon materials was investigated. Porous carbon materials were prepared by using glucose as carbon source

and then characterized. Kinetic curves of anisole desorption on glucose-based porous carbon materials were measured. Model for estimating diffusion coefficient of anisole desorption from the carbon materials was established. Results showed that the specific surface area of the prepared samples reached as high as 1133-3153 m2·g−1

and the anisole adsorption capacity of the adsorbents reached as high as 1050 mg·g−1. Anisole desorption from the samples took place by mechanism of bulk diffusion

Knudsen diffusion and surface diffusion. The textural structure of the porous carbons had influence on the diffusion mechanism of anisole desorption. The high proportion of micropores would make the more anisole molecules desorb in the form of surface diffusion. Knudsen diffusion and surface diffusion played an important role in release-slowing anisole from the samples. About 78%-83% of anisole desorbed from the porous carbons in the forms of Knudsen diffusion and surface diffusion.
