| Abstract: | OBJECTIVE: To establish a new method for measuring the content of benzalkonium bromide in disinfectant so- lution METHODS: The sodium nitrite was removed from disinfectant solution by reaction between sodium nitrite and urea to form N2 and CO2 and then benzalkonium bromide in the solution was directly determinated by UV-spectrophotometry with no need of separation RESULTS:There was no significant difference between this method and the method in pharmacopeia CON CLUSION:The method is simple, rapid and accurate and can be used to measure benzalkonium bromide in the solution. |
