Abstract
In thhis paper,a novel coated carbon clorprenaline hydrochloride(CLP)ion selective electrode based on Fe3O4 nanoparticles as the modifier for the rapid determination of CLP was first prepared.The characteristics of the Fe3O4 nanoparticles modified electrode were detected by potentiometric analysis and cyclic voltammetry method.The results shown that the response of CLP on the Fe3O4 nanoparticles modified electrode was enhanced conspicuously,the linear response range was from1.0×10-6 to 1.0×10-1 mol/L with a slope of 52 mV/pC,and the detection limit was 8.0×10-7mol/L.Comparing with the unmodified coated carbon electrode,the Fe3O4 nanoparticles modified electrode shown better characteristics in detection limit and linear response range.These rusults reavel that the Fe3O4 nanoparticles modified electrode can be successfully employed to detect CLP in pork samples and the results were in agreement with HPLC-MS.
