| Abstract: | A simple and fast method for the determination of trace nitrite was developed based on the reaction of nitrite with the resorcinol and the zirconium oxygen ion to create a colored chelate under the acidic condition.The influence of wavelength,acidity,concentration of color reagents and coloration time on the absorbence were studied and the experimental conditions were optimized,which is confirmed by normal experimental design.The method was used to deal with the pork,lunch meat,sausage sample with the recovery over 90%. |
