摘要
建立了一种紫外分光光度法测定氯化胆碱·萘乙酸可湿性粉剂中萘乙酸含量的方法。实验结果表明,萘乙酸的浓度与吸光度有良好的线性关系,该方法的相对标准偏差为1.64%,回收率范围在97.4%~104.6%,简便可行,灵敏度高。
A method is established for the dtermination of naphthylacetic acid in choline chloride·naphthylacetic acid WP by ultraviolet spectrophotometry.The concentration of naphthylacetic acid has good linear relationship with absorbance.The recovery is 97.4%~104.6% and the RSD is 1.64%.The method is simple and workable.
