复方氯霉素酊液是由氯霉素和水杨酸组成的复方制剂,临床应用较广泛,其含量测定方法目前尚未见报道。根据氯霉素和水杨酸在紫外区有强吸收的特点,我们设计了应用联立方程分光光度法,不经分离,仅测定两个波长处的吸收度值,根据吸收度加和原则,联立方程求解,即可计算氯霉 Compound chloramphenicol tincture is composed of chloramphenicol and salicylic acid compound preparation, clinical application is more extensive, the determination of content has not been reported. According to the strong absorption of chloramphenicol and salicylic acid in the ultraviolet region, we designed the simultaneous equation spectrophotometry, without separation, only the absorption values ​​at two wavelengths were measured. According to the principle of absorption plus, Simultaneous equation solving, you can calculate the chlorine mold
