The determination of food additives is one of the major points in the food industry that directly is relative to human health. This research work focused on sensing and monitoring sunset yellow as azo additive dyes in fruit juices using an electrochemical sensor amplified with Ni doped Pt decorated carbon nanotubes (NiO/Pt/CNTs) as nano-catalyst and 1-hexyl-3-methylimidazolium chloride ([HMIM][Cl]) as an ionic liquid binder. Carbon paste electrode (CPE) amplified with NiO/Pt/CNTs and [HMIM][Cl] (CPE/([HMIM][Cl])/NiO/Pt/CNTs) improved the sensitivity of sunset yellow sensing in aqueous solution in acidic condition and successfully monitored this azo dye in concentration range 1.0 nM-280 μM with detection limit 0.4 nM. On the other hand, the CPE/([HMIM][Cl])/NiO/Pt/CNTs was used for sensing and analysis of sunset yellow in different fruit juices, and recovery data between 98.65% and 103.66% confirmed the powerful ability of sensor for monitoring of sunset yellow in food samples.
食品添加剂的测定是食品工业中的一个重要环节，直接关系到人类健康。本研究工作集中于使用电化学传感器检测和监测果汁中的日落黄作为偶氮添加剂染料，该传感器通过掺杂 Ni 的 Pt 修饰的碳纳米管 (NiO/Pt/CNTs) 作为纳米催化剂和 1-己基-3-甲基咪唑氯 ([HMIM][Cl]) 作为离子液体结合剂进行放大。NiO/Pt/CNTs 和 [HMIM][Cl] 增强的碳糊电极 (CPE/([HMIM][Cl])/NiO/Pt/CNTs) 提高了在酸性条件下检测日落黄的灵敏度，并成功地在 1.0 nM-280 μM 的浓度范围内监测到这种偶氮染料，检测限为 0.4 nM。另一方面，CPE/([HMIM][Cl])/NiO/Pt/CNTs 用于检测和分析不同果汁中的日落黄，回收率数据在 98.65%和 103.66%之间，证实了传感器在食品样品中监测日落黄的强大能力。
