## Abstract **Summary:** Starting from 5 wt.‐% solutions of a prehydrolysis kraft pulp ($\overline M \_{\rm n}$ = 135 kg · mol^−1^) in the mixed solvent (dimethylacetamide + 7 wt.‐% LiCl) we have prepared cellulose membranes on different supports according to the phase inversion process using above
Dissolution profiles are classified in accordance with the shape of fractional dissolution rate function. This function is constant in time for the classical first-order model and, in this case, the dissolution is described by a monoexponential function. Therefore, any deviation of the fractional di
