ZnO-CuO nanoplates and 2-chlorobenzoyl ferrocene, were synthesized and used to construct a modified carbon paste electrode. The electrooxidation of 6-thioguanine at the surface of the modified electrode was studied. Under the optimized conditions, the square wave voltammetric (SWV) peak current of 6-thioguanine increased linearly in the concentration range 0.05 to 200.0μM and detection limit of 25±2nM was obtained for 6-thioguanine. The prepared modified electrode exhibits a very good resolution between the voltammetric peaks of 6-thioguanine and folic acid which makes it suitable for the detection of 6-thioguanine in the presence of folic acid in real samples.
合成了氧化锌-氧化铜纳米片和2-氯苯甲酰二茂铁，并用于构建修饰碳糊电极。研究了修饰电极表面6-硫鸟嘌呤的电氧化。在优化条件下，6-硫鸟嘌呤的方波伏安（SWV）峰电流在0.05至200.0μM浓度范围内呈线性增加，6-硫鸟嘌呤的检测限为25±2 nM。所制备的修饰电极在6-硫鸟嘌呤和叶酸的伏安峰之间表现出非常好的分辨率，这使得它适用于在实际样品中存在叶酸的情况下检测6-硫鸟嘌呤。
