摘　　要：以氯仿作为溶剂,采用紫外分光光度法对盐酸普罗帕酮片的含量进行测定.实验结果表明,盐酸普罗帕酮在0.016 8~0.303 1 mg/mL范围内吸光度与浓度呈良好的线性关系,回归方程为A=12.76c+0.566 8,相关系数r=0.999 4.与其它方法相比,本法具有仪器简单、方法简便快速、重现性好、回收率高的特点.与乙醇做溶剂相比较,线性范围加宽,可直接测定高浓度样品.An UV Spectrophotometry was used for the determination of propafenone iydrochloride in tablet under chloroform as solvent.Beer′s law was obeyed in the range of 0.0168～0.3031mg/mL for propafenone hydrochloride,the equation of linear regression is A=12.76c+0.566 8,and r=(0.999 4).Compared with other methods,the method is simple,rapid,good repeatability and high recovery.The linear range is wider compared with alcohol as solvent in reference,and the sample in high concentration of propafenone hydrochloride can be determined directly.
