摘要
目的:建立苯扎溴铵滴眼液中苯扎溴铵的含量测定方法。方法采用紫外分光光度法测定含量,以262.0nm处为测定波长测定吸收度。结果在0.1~0.6mg/ml之间呈良好线性关系,相关系数γ=0.9998,平均回收率为99.7%,RSD为0.45%。结论该法简便、准确,重现性好,可用于苯扎溴铵滴眼液的定量测定。
Objective:To establish an assay method for the determination of Benzalkonium Bromide in Benzalkonium Bromide Eye Drops.Methods:The content of Benzalkonium Bromide was determined by ultraviolet spectrophotometry. The absorbency was measured at262.0nm.Results:The calibration curve was linear within 0.1-0.6mg/ml (v = 0. 9998).The average recovery was 99.7%(n=5),and the RSD was 0.45%.Conclusion:The method was proved to be simple,precise and reproduciable.It can be used for the quantitative determination of Benzalkonium Bromide Eye Drops.
