摘　　要：采用热丝化学气相沉积法(HFCVD)制备了掺硼金刚石(BDD)电极,将其用于检测四溴双酚A(TBBPA)。表面活性剂CTAB对检测过程具有良好的增敏效果,经优化后选取其浓度为10μmol/L。响应峰电流与四溴双酚A浓度在20~500nmol/L的范围内呈现非常好的线性关系,相关系数为0.9950,检测下限为4nmol/L。检测过程呈现良好的重复性。A boron-doped diamond(BDD)electrode manufactured by hot filament chemical vapor deposition(HFCVD)is used for detection of tetrabromobisphenol A(TBBPA).CTAB,which is one kind of surfactant,had a great enhancement effect on the detection.After optimization,the concentration of CTAB is selected to be 10μmol/L.The response peak current shows a very good linear relationship with the concentration of tetrabromobisphenol A in the range of 20~500nmol/L with correlation coefficient of 0.9950 and a detection limit of 4nmol/L.The detection process is well reproducible.
