摘要：

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.
