【摘要】 提出了双嘧达莫与高锰酸钾和罗丹明B的化学发光新体系 ,并发现表面活性剂吐温 80可显著增强该体系的化学发光 ,据此建立了流动注射化学发光测定双嘧达莫的新方法。该方法选择性好 ,灵敏度高 ,线性范围宽 ,双嘧达莫在 5 0× 10 -8～ 5 0× 10 -5g·mL-1范围内与发光信号呈线性关系 ,检出限 1 7× 10 -8g·mL-1,RSD为 1 1% (n =11,cs=1 0× 10 -6g·mL-1双嘧达莫浓度 )。更多还原

【Abstract】 A new system for the determination of dipy ri damole with flow injection chemiluminescence was described. It is based on the chemiluminescence reaction of dipyridamole-potassium permanganate with rh odamine B. Tween-80 was found to be an enhancer of the chemiluminescenc e reaction. A method based on the enhanced chemiluminescence for dipyridamole determination has been developed. The method has high sensitivity,selecti vi ty and good repeatability with a linear concentration range of 5.0×10~-8 -5.0×10~-5 g·mL~-1 ,a detection limit of 1.7×10~-8 g ·mL~-1 and a RSD of 1.1%( n =11,c _s=1.0×10~-6 g·m L~-1 ).更多还原
