摘要：

Based on our previous studies which indicated a strong interaction between 8-amino-N-(2-hydroxybenzylidene) naphthyl amine (ANA) with La(III) ions, ANA was used as a sensing material in a nano-composite based carbon paste electrode. The electrodes were made based on a nano-composite including multi-walled carbon nanotube (MWCNT), graphite, and room temperature ionic liquid (RTIL), 1-n-butyl-3-methylimidazolium tetrafluoroborate [bmim]BF(4). The best results were obtained for the nano-composite sensor with electrode composition of 5% MWCNT, 10% ANA, 15% RTIL, and 70% graphite powder. The proposed sensor shows a Nernstian response (19.8 +/- 0.3 mV decade(-1)) in the range of 1.0x10(-6)-1.0x10(-2) M with detection limit of 8.0x10(-7) M. The response of the sensor is independent of pH in the range of 4.0-9.0. The nano-composite based La(III) sensor displayed good selectivity, response time, and lifetime.
