| Abstract: | The effects of salicylic acid（SA） and methyl salicylate（MS） on blocking synthesis of nitrosamine were studied by ultraviolet photolysis,and compared with ascorbic acid（Vc） with the same condition.The effects of determination conditions such as concentrations,reaction time,pH value and ultraviolet radiation wavelengths on blocking nitrosamines by SA、MS were investigated.The results showed that：when reaction time was 1 h,pH value was 3.00,reaction temperature was 37 ℃,reaction concentration was 1.28 mmol/L,ultraviolet radiation wavelengths was 254 nm,their blocking rates could reached the highest.The blocking capability followed by：Vc〉MS〉SA. |
