Porous cyclodextrin-based polymers are widely used for the rapid removal of organic pollutants in water. Traditional cyclodextrin-based polymers were prepared in the organic phase, which is time-consuming and high-cost. In this paper, we designed a novel cyanuricchloride (TCT) crosslinked porous β-cyclodextrin-based thin-film composite membrane in the aqueous phase by interfacial polymerization. A self-standing TCT-CDP film was formed instantly at the surface of water phase at room temperature. Several different water-soluble organic dyes such as Methylene Blue, Neutral Red, Auramine, Brilliant Green and Crystal Violet were selected for rejection study with TCT-CDP membrane. The effective rejection of TCT-CDP membrane for typical dyes is up to 99%, indicating TCT-CDP membrane exhibit excellent selectivity for separation of organic dyes from water.
