Determination of Cyromazine and Melamine Based on Capillary Electrophoresis Coupled with Electrogenerated Chemiluminescence at Gold Nanoparticles Modified Electrode

Abstract:

A method has been developed for the detection of cyromazine and melamine using capillary electrophoresis (CE) coupled with electrogenerated chemiluminescence (ECL). The method utilized gold nanoparticles modified electrode as a working electrode because it can improve sensitivity of ECL detection. It has been found that acetonitrile can improve stacking in electrokinetic injection with field amplified sample stacking. The detection limits of 0.5 ng/mL and 1.0 ng/mL were obtained for cyromazine and melamine, respectively. The established method was successfully applied for milk sample analysis with good reproducibility, precision, accuracy, and high recovery.
