新型分子印迹敏感膜传感器直接快速检测饮料中的柠檬黄
A Novel Sensor for Fast and Direct Determination of Tartrazine in Soft Drinks Based on Molecularly Imprinted Film
摘要
Abstract
A novel molecularly imprinted polymer sensor(MIP-PmDB/PoPD-GCE)for fast and direct tartrazine(TZ)de-termination was developed.The polymer was coated on the surface of the glassy carbon electrode(GCE)directly via electro-polymerization,with m-dihydroxybenzene(m-DB)and o-Phenylenediamine(o-PD)as monomers.The new sensor can be bound to tartrazine in real samples without sample pretreatment.The molecularly imprinting effect was characterized with cyclic voltammetry(CV)and electrochemical impedance spectroscopy(EIS).The response performance was studied with differential pulse voltammetry(DPV).The linear relationship between the current and the tartrazine concentration was ob-served from 5.0×10-9mol/L to 1.1×10-6mol/L,with the detection limit of 3.5×10-9mol/L and detection timeof 5,min.The new sensor was successfully applied to the analysis of tartrazine in soft drink samples and the recovery rate was between 96.35%, and 101.32%.关键词
