The heat and mass transfer in the sublimation problem of a Ficks porous slab under the first boundary condition was studied by the use of perturbation method. From a new treatment of the boundary conditions at the moving interface proposed by the authors
the analytical expressions of the dimension-less temperature
concentration and the position of moving interface could be developed. The pertur bation solution approached the experimental results better than the quasi-steady model.
