| 摘要 |
The invention relates to a membrane that is selective for anions, particularly phosphate, comprising an ionophore based on a uranyl complex with the annexed general formula, wherein A, B, C, D=R A+B+C+D=(C5-C7) aryl, (C5-C7) cycloalkyl, (C1-C30) alkyl (C5-C10) aryl, (C1-C30) alkyl (C5-C10) cycloalkyl, E+E', G+G'=aryl, such as phenyl and naphthyl, or aryl substituted with a substituent (C1-C30) alkoxy, or aryl substituted with the individual substituent or the substituent joined by ring closure K and/or K-CONH-L, wherein K, L=H -R-(CH2)m-, -R-(CH2)m-R, -X-(CH2)m-, -X(CH2)m-R, -X-(CH2)m-X, -X(CH2)m-X-R, -RX(CH2)m-, -RX(CH2)m-XR, -X-(R-X)n-, wherein X=O, S; m= 0-10 and n= 0-10 R=(C1-C30) alkyl, (C5-C10) aryl, (C5-C10) cycloalkyl, (C1-C30) alkyl (C5-C10) aryl, (C1-C30) alkyl (C5-C10) cycloalkyl, wherein alkyl is a straight or branched chain and wherein aryl and alkyl are optionally substituted with (C1-C30) alkyl halogen nitro cyano hydroxy. <IMAGE>
