摘要：

A PVC membrane electrode for aluminium ion based on bis(5-phenyl azo salicylaldehyde) 2,3-naphthalene diimine (5PHAZOSALNPHN) as an ion carrier was developed. The electrode exhibits a Nernstian slope of 19.3 +/- 0.8 mV per decade and a linear range of 5.0 x 10(-6)-1.0 X 10(-2) M for AI(NO,),. The limit of detection is 2.5 x 10(-6) M. It has a fast response time of about 10 s and can be used for at least 10 weeks without observing any deviation. The proposed membrane sensor revealed good selectivity for Al3+ over a wide variety of other metal ions and could be used in pH range of 2.9-5.0. It was used as an indicator electrode in potentiometric titration of aluminium ion. (C) 2002 Elsevier Science B.V. All rights reserved.
