我国的水资源日益短缺.为缓解供水不足的紧张局面,可进行污水的深度处理回用.膜分离是一种有效的回用方法,但膜易受污染,导致通量下降.作者采用溶胶-凝胶法制备了耐污染性强的SiO2/聚砜复合膜,并对其进行了性能表征.SEM图像显示该膜具有双皮层不对称结构,膜内均匀分散有SiO2粒子,该粒子既能增强膜的强度,又能提高膜的耐污染能力.以自来水对该膜进行了水通量测试,测试表明所制膜水通量较高,在0.10 MPa下可达250~300L/(m2·h). 相似文献

Chitoson, a high molecular weight polymer, has the ability to sorb metals and form chitosan-metal complexes. A complex using copper has been prepared and its desorption characteristics have been studied. The slow release of copper is of potential use in anti-fouling paints and therefore the desorption of copper has been studied under various environmental conditions. Desorption rates were high in distilled water but low in sea water, and after further comparative tests with commercial marine paints, it was concluded that copper-chitosan complexes are not as effective as the cuprous oxide anti-fouling agent currently used in marine paint formulations. 相似文献
