Industrial processes often generate a large amount of alkaline waste solutions. The existing alkali treatment processes require high investment, and are complicated and have a low rate of efficiency. Membrane technology has the advantages of high efficiency and energy savings. However, current polymeric membrane materials are not strong enough in harsh alkaline environments. To solve this problem, Prof. Li Pei from Beijing University of Chemical Technology and Dr. Jianzhong Xia from Shenzhen University have developed an alkali-resistance pervaporation membrane. The relevant work was published in Frontiers of Chemical Science and Engineering on March 28, 2022.
