Abstract: 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.
