Abstract:
Water pollution seriously affects the development of society and human life. There are various kinds of pollutants, including soluble pollutants and insoluble floaters on the water surface. Herein, the photocatalyst semiconductor BiOCl and superhydrophobic functional particles Mg(OH)2 were deposited on the surfaces of canvas and polyester felt to construct superhydrophobic canvas and polyester felt. The contact angles of the synthetic superhydrophobic canvas and polyester felt were measured as 152° and 155.3°, respectively. The selective adsorption of hexadecane was achieved using the wetting difference between the surface of water and pollutants floating on the surface. For dissolved pollutants, the surface wettability needed to be changed with the help of ethanol. The degradation efficiencies were all greater than 90%, demonstrating the versatility of the synthetic superhydrophobic canvas and polyester felt.
摘要:
水污染严重影响着社会的发展和人类的生活。有各种各样的污染物,包括水面上的可溶性污染物和不溶性漂浮物。在这里,将光催化剂半导体BiOCl和超疏水功能颗粒Mg(OH)2沉积在帆布和聚酯毡表面,构建超疏水帆布和聚酯毡。合成的超疏水帆布和聚酯毡的接触角分别为152°和155.3°,分别。利用水表面和漂浮在表面上的污染物之间的润湿差异,实现了十六烷的选择性吸附。对于溶解的污染物,表面润湿性需要在乙醇的帮助下改变。降解效率均大于90%,展示了合成超疏水帆布和聚酯毡的多功能性。
