Electrochemical Sensor Based on Platinum-Nickel-Iron/Carbon Nanosheets Nanocomposite for Determination of Clenbuterol
By using ehanolamine and oleylamine as reduction,dicaprylyl ether and 1,2-hexadecanediol as medium,PtNiFe(8-13 nm) nanoflower-particles were prepared.By utilizing a graphite rod as a carbon source and quench method to get the carbon nanosheets,the clenbuterol electrochemical sensor was prepared by absorbing PtNiFe nanoflower onto carbon nanosheets to modified carbon glassy electrode for the detection of clenbuterol residual in the metabolite of animal.The effects of some experiment conditions such as buffer,enrichment potential and time on the electrochemical behavior of this sensor were investigated.The liner range was 1.9×10-7-4.9×10-2 mol/L,and the detection limit is 6.0×10-8 mol/L.This sensor has good selectivity,high sensitivity,good reproducibility and stability.
