摘要
本文研究了多巴胺在聚组氨酸修饰电极上的循环伏安行为.在pH7.0的磷酸盐缓冲溶液中,用线形扫描伏安法测定多巴胺的线性范围为:6.0×10-8~1.0×10-5mol/L,1.5×10-5~1.0×10-3mol/L,检出限为4×10-8mol/L.用于药剂中多巴胺的测定,结果满意.
In this paper, the cyclic votammetric behavior of dopamine on the poly(histidine) modified electrode is studied. In pH 7.0 phosphate buffer solution, the linear response range of dopamine is about 6.0×10-8~1.5×10-5mol/L and 1.5×10-5~1.0×10-3mol/L.The detection limit is 4.0×10-8mol/L.This method has been applied to the determination of dopamine in drug with satisfactory results.
