The present invention relates to a process for purifying a slurry comprising cellulose, such as microfibrillated cellulose, wherein the process comprises the following steps: -providing a slurry comprising cellulose and liquid, -subjecting the slurry to an electric field inducing the liquid of the slurry to flow, -separating the liquid from the cellulose thus obtaining a liquid depleted slurry, -adding a washing liquid, such as an organic solvent, to the liquid depleted slurry-subjecting the liquid depleted slurry to an electric field inducing the washing liquid of the slurry to flow and-separating the washing liquid from the cellulose, thus obtaining a purified cellulose. The invention also relates to cellulose such as microfibrillated cellulose obtainable from said process. |
