摘要
提出了一种用紫外光度法同时测定盐酸西替利嗪和苯甲酸钠的方法。在pH 4.56的B-R缓冲溶液中对盐酸西替利嗪和苯甲酸钠两组分混合溶液进行吸光度测定,所得的重叠光谱数据用主成分回归法(PCR)和偏最小二乘法(PLS)等化学计量学方法进行处理,结果表明主成分回归(PCR)的预报误差最小。对实际样品进行测定,回收率为88.87%～105.87%。
A method of simultaneous determination cetirizine hydrochloride and sodium benzoate by UV - spectrophotometry was introduced. With the aid of some chemometric approaches, it is possible to determine these two compounds simultaneously by UV - spectrophotometry in a B - R buffer medium of pH 4.56. The optimum conditions for the determination of each component were eval- uated. The principal component regression （PCR） method was found to give more accurate results as compared with the PLS method. The recoveries of determination actual samples were in the range of 88.87% - 105.87%.
