摘要：

Potentiometric modified screen-printed electrodes were developed for UO2(II) determination using a triazole-derivative alone (MSPE) or self-assembled on silver nanoparticles- (SNPs-MSPE). The electrodes exhibited excellent potentiometric response characteristics with Nernstian slopes of 26.70 +/- 1.02 and 29.90 +/- 0.88 mV decade(-1) and detection limits of 1.00 x 10(-7) and 6.10 x 10(-10) mol L-1 for MSPE and SNPs-MSPE, respectively. The electrodes showed fast response times and independent response over a wide pH range. Effect of solution temperature was investigated in the range of 10-60 A degrees C. The optimized electrodes revealed good selectivity for UO2(II) over various interferant and were successfully employed to detect UO2(II) in different real samples.
