摘要

采用电渗法研究了电解质溶液组分对铝阳极氧化多孔膜层界面电性能的影响.结果表明,多孔膜分别经含F-、PO3-4、SiO2-3或单宁酸溶液浸泡处理后,膜在0.01mol/LKCl溶液中的等电点由原来的pHIEP=9.20分别移至pHIEP=3.40,4.30,3.30和4.50;pH<pHIEP时,多孔膜荷正电,pH>pHIEP时多孔膜荷负电,膜的ζ电位—pH曲线也发生了变化.经酸性品红和碱性品红溶液浸泡后的多孔膜,在2.0<pH<11.0范围无等电点,膜的ζ电位始终大于零(碱性品红浸泡),ζ电位始终小于零(酸性品红浸泡).

Abstract

The influence of electrolytic composition on the interfacial electric Characteristic of the porous membrane membrance of anodized aluminum was investigated with a electrodialytic method. Results indicated that, when the porous membrane was pretreated with F -, PO 3- 4,SiO 2- 3 and tannic acid, the isoelectric point in 0.01 mol/L KCI, were shifted from normal 9.20 to 3.40, 4.30, 3.30 and 4.50, respectively, and responsive characteristics of ζ potential to pH was changed. Furthermore, after pretreatment of porous membrance with fuchsine basic and fuchsine acid solution,there was no isoelectric point at 2.0<11.0, and the ζ potentials were positive and negative, respectively.
