Applicability of square wave voltammetry for the determination of Cu(II) ions by PolyLut/GC and PolyKae/GC electrodes was evaluated in this study. For this luteolin and kaempferol were electrochemically polymerized on glassy carbon (GC) electrode surface in order to get polyluteolin and polykaempferol-modified glassy carbon electrodes (PolyLut/GC and PolyKae/GC, correspondingly). The formation of polyphenol layer on the GC electrode surface was evidenced by atomic force microscopy. Square wave voltammetry was found to be more sensitive in comparison with differential pulse voltammetry. It was determined that PolyLut/GC and PolyKae/GC electrodes offered great sensitivity towards Cu(II) ions with very low limit of detection, good reproducibility, sufficient stability and excellent selectivity of analytical signal.
本研究评估了方波伏安法在聚芦丁/GC 和聚山奈酚/GC 电极测定 Cu(II)离子中的适用性。为了得到聚芦丁和聚山奈酚修饰的玻碳电极（PolyLut/GC 和 PolyKae/GC），本研究中将芦丁和山奈酚电化学聚合在玻碳电极表面。原子力显微镜证实了在 GC 电极表面形成了多酚层。与差分脉冲伏安法相比，方波伏安法的灵敏度更高。结果表明，PolyLut/GC 和 PolyKae/GC 电极对 Cu(II)离子具有很高的灵敏度，检测限低，重现性好，稳定性足够，分析信号选择性好。
