离子印迹磁性碳纳米球基电化学传感器用于铜(Ⅱ)的选择性检测
A highly selective and sensitive electrochemical Cu(Ⅱ)detector based on ion-imprinted magnetic carbon nanospheres
摘要
Abstract
An electrochemical sensor for Cu(Ⅱ)based on ion-imprinted polymers was prepared by combining surface imprinting with electrochemical polymerization deposition.The sensor was modified by ion-imprinted magnetic carbon nanospheres with a spe-cific selectivity and sensitivity for Cu(Ⅱ).The morphology and structure of the materials were characterized and analyzed.Sensors with the imprinted electrode had a stronger selectivity and higher sensitivity towards Cu(Ⅱ)compared with their original counter-parts.Within relative concentrations of Cu(Ⅱ)from 10-6 to 10-10 mol L-1,the detection limit of the sensor was as low as 5.138×10-16 mol L-1(S/N=3).The sensor is resistant to interference,and has good reproducibility,and stability,making it excellent for the electrochemical detection of metal ions.关键词
