A new and progressive electroanalytical sensor was made by the incorporation of Pt‐doped NiO nanoparticle (Pt‐NiO‐NPs) into carbon paste electrode (CPE) amplified with 1‐hexyl‐3‐methylimidazolium tetrafluoroborate (1H3MTFB) as a conductive binder. The Pt‐NiO‐NPs/1H3MTFB/CPE caused an extraordinary rise in the oxidation peak current of epinine (∼4.6 times) and simultaneous reduction in the oxidation over‐potential of catecholamine drug (∼120 mV). SWV method was employed to investigate the ability of Pt‐NiO‐NPs/1H3MTFB/CPE as an electroanalytical sensor in the determination of epinine in the presence of phenylephrine as two blood pressure raising drugs with ΔE=280 mV for the first time. Experimental results pertinent to SW voltammetric investigation reveal a linear relation between epinine and phenylephrine currents and drugs concentration in the rages 0.004–450 and 0.02–350 μM, respectively.

掺杂Pt的NiO纳米粒子离子液体修饰的电化学传感器：在苯肾上腺素作为两种降压药的情况下测定依皮宁的有效方法

通过将Pt掺杂的NiO纳米颗粒（Pt-NiO-NPs）掺入碳糊电极（CPE）中，并用1-己基-3-甲基咪唑四氟硼酸酯（1H3MTFB）作为导电粘合剂进行放大，制成了一种新型的电分析传感器。Pt-NiO-NPs / 1H3MTFB / CPE导致表胺的氧化峰电流异常升高（约4.6倍），同时降低了儿茶酚胺药物的氧化过电位（约120 mV）。SWV方法被用于研究Pt-NiO-NPs / 1H3MTFB / CPE在存在苯肾上腺素作为两种降压药物的首次确定ΔE= 280 mV的情况下测定电子分析中的能力。
