Ultraviolet Spectrophotometric Assay for Benzalkonium Bromide in Benzalkonium Bromide Eye Drops

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 (γ=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.
