提出了以四阶导数光谱法测定苯甲醇注射液中苯甲醇的方法。当苯甲醛的含量小于160μg/ml时,不干扰苯甲醇的测定,苯甲醇含量在180~400μg/ml范围内时,呈良好线性关系,三次测量的相对标准偏差小于05%,标准回收率在99%~101%以内.
A method for the determination of benzyl alcohol in benzyl alcohol injection by fourth derivative spectroscopy was proposed. When the content of benzaldehyde was less than 160μg / ml, the determination of benzyl alcohol was not disturbed. When the content of benzyl alcohol was in the range of 180 ~ 400μg / ml, the relative standard deviation was less than 05% The standard recovery rate is within 99% ~ 101%.
