These i mprovements are investigated when F-and Fe2+are used inprocesses. The experi mental results show that the F-can slow down the release rate of Pb2 +in depositionprocess and make the catalytic coating compact, uniform, adhesion tigh. t The Fe2+hasbetter effect than F-inthis side. Because of ultrasonic stirring, Pb and Fe distributions are uniform in coating and become the idealform of βPbO 2 ion-membrane electrode.[ Key words] 　Ion-membrane electrode;β PbO 2 ;Additive;Surface structure[ 收稿日期] 2006 - 03 - 03[ 基金项目] 河南省杰出人才创新基金项目(521001400)[ 作者简介] 万亚珍(1963 - ),女, 陕西礼泉人, 副教授, 博士, 主要从事膜技术和环境保护方面的研究工作。
