| Abstract: | PtNi nanoparticles were synthesized by solvent thermal method and electrochemical sensor was prepared by nanoparticles modified on glassy carbon electrode,which is used for detection bisphenol A.In order to opmizied experimental conditions,buffer solution,enrichment potential and enrichment time have been investigated for the effect of electrochemcial sensor on the performance.The experimental results show that,the oxidiation potential is 0.5 V,the linear range of the sensor to detect bisphenol A is 0.99-99.9 ×10-6mol/L;the detection limit is 3.36 × 0-7mol/L,the sensor has good selectivity,high sensitivity,good reproducibility and stability. |
