中文摘要：
以1,2-二羟基十六烷作为反应介质,油胺和油酸作为还原剂,制备出8～13 nm的PtNiFe三金属纳米花颗粒,并以石墨棒作为碳源,通过高温淬火制得碳纳米片;将三金属纳米花颗粒吸附在碳纳米片的表面,并将其修饰到玻碳电极表面,制备了盐酸克伦特罗电化学传感器,用于动物代谢中的盐酸克伦特罗残留量的直接电化学检测。探讨了测试底液、富集电位以及富集时间等实验条件对传感器性能的影响。结果表明,在电位为0.4 V条件下,传感器检测盐酸克伦特罗的线性范围为1.9×10＂7～4.9×10＂2mol/L;检出限为6×10＂8mol/L。此传感器选择性好、灵敏度高,具有良好的重现性和稳定性。
英文摘要：
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 clenbutcrol 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 1.9x10-7-4.9x10-2 mol/L, and the detection limit is 6.0xl0-s mol/L. This sensor has good selectivity, high sensitivity, good reproducibility and stability.
