研究了聚亚甲蓝修饰碳纤维微电极同时测定多巴胺和抗坏血酸的分析方法 ,在该修饰电极上 ,多巴胺和抗坏血酸均具有高的灵敏度 ,并且在电极反应过程中不沾污电极 ,重现性好 ,测定过程无需除氧 ,这对于生物活体在线检测是一个非常重要的条件
The method for the simultaneous determination of dopamine and ascorbic acid by using poly (methylene blue) modified carbon fiber microelectrode was studied. Both dopamine and ascorbic acid have high sensitivity and do not contaminate the electrode during electrode reaction. The method has good reproducibility, No oxygen scavenging process, which is a very important condition for on-line biological testing
