| Abstract: | Objective: To establish the determination of sodium nitrite in benzalkonium bromide solution for disinfection. Methods: The sodium nitrite was determined at 354 nm with water solution. Results: The concentration of sodium nitrite to UV absorption was linear between 0.4 mg/ml to 2.4 mg/ml. The average recovery was 99.8% with RSD 0.4%. Conclusion: The UV spectrophotometry is accurate for the determination of sodium nitrite in benzalkonium bromide solution for disinfection. |
| Keywords: | benzalkonium bromide solution for disinfection sodium nitrite UV spectrophotometry |
