    Unfortunately, imidazole‐based ionic liquids (ILs) tend to build high‐boiling impurities like chromophores. This results in reduced process stability and product conditions like stained cellulose fibers. Therefore, different adsorbent materials were tested for their capability to purify the IL 1‐ethyl‐3‐methylimidazolium acetate. The product quality was monitored by UV‐vis spectroscopy. It was observed that activated carbon showed the best purification results. The purified IL was successfully reused in the process of cellulose dissolution and shaping.
