采用单宁酸功能化n掺杂石墨烯（TA/N-G）修饰的玻碳电极（GCE），研制了一种快速、环保、灵敏的双酚A （BPA）检测传感器。与其他传感器相比，由于N-G的活性表面积和TA的高吸收效率，该传感器大大增强了BPA的响应信号。在最优条件下，在0.05 ~ 13 μ M范围内，氧化电流随BPA浓度的增加呈线性增加，检测限为4.0 nM。该电极具有良好的重现性、稳定性和抗干扰性。所研制的电化学传感器成功地应用于食品包装中BPA的检测。(C) 2014 Elsevier B.V.版权所有
A rapid, environmental friendly, and sensitive sensor for the detection of bisphenol A (BPA) was developed at glassy carbon electrode (GCE) modified with Tannic acid functionalized N-doped graphene (TA/N-G) immobilized by Nafion. Compared with other sensors, the proposed sensor greatly enhanced the response signal of BPA due to the active surface area of N-G and high absorption efficiency of TA. Under the optimal conditions, the oxidation current increased linearly with increasing the concentration of BPA in the range of 0.05-13 mu M with the detection limit of 4.0 nM. The fabricated electrode showed good reproducibility, stability and anti-interference. The developed electrochemical sensor was successfully applied to determine BPA in food package.
