In this article, a simple, low\u2010energy, and low\u2010cost strategy is proposed for the effective separation of acetonitrile from high\u2010concentration acetonitrile wastewater. The approach is based on a sequential combination of two steps: salt\u2010induced phase separation and hydrophobic filtration. The acetonitrile wastewater was first induced to split into two phases by salt, that is, the acetonitrile\u2010rich phase and the water\u2010rich phase, then the above two phases were poured into the hydrophobic filter paper funnel for the separation. It was shown that NaCl is a suitable salting\u2010out reagent, and that hydrophobic filter papers\u2014obtained from modification by butyltrichlorosilane and octyltrichlorosilane were the optimal choice for hydrophobic filtration. The salt\u2010induced phase separation process is able to increase the volume fraction of acetonitrile in the acetonitrile\u2010rich phase up to 92%. The acetonitrile\u2010rich phase can pass through the hydrophobic filter paper, whereas the water\u2010rich phase was intercepted. The hydrophobic filter paper retained strong hydrophobicity and high acetonitrile\u2010separating capacity after 3 months storage, or upon immersion in acetonitrile\u2010water mixtures for 12\u00a0h, or applied for 25 consecutive separations.<\/jats:p>","DOI":"10.1002\/jssc.202300426","type":"journal-article","created":{"date-parts":[[2023,8,19]],"date-time":"2023-08-19T00:30:39Z","timestamp":1692405039000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["A simple and low\u2010energy strategy for the separation of water and acetonitrile"],"prefix":"10.1002","volume":"46","author":[{"given":"Mincong","family":"Liu","sequence":"first","affiliation":[{"name":"Key Laboratory of Chemical Biology &amp; Traditional Chinese Medicine Research of Ministry of Education and Key Laboratory of Phytochemical R&amp;D of Hunan Province Hunan Normal University  Changsha P.
