摘要：
Micro-fabrication and characterization of new organic membrane and titanium dioxide nano-particles hybrid based copper (II) micro-sensor have been demonstrated. The realized nano-composites based thin-film micro-sensor incorporates titanium dioxide nano-particles as sensitive materials, poly (vinyl chloride) as supporting matrix and 2-nitrophenyl octyl ether as plasticizer. The micro-sensor based on these materials provides near Nernestian response for copper (II) ions (sensitivity of 23 +/- 0.5 mV/concentration decade) covering the range of 10(-1)-10(-5) mole L-1 and detection limit of 4.75x10(-6). The developed thin-film micro-sensors was successfully used in the determination of copper (II) in some samples with high accuracy (97%) and precision (<3%).
