Title: Determination of nitrite using methylene blue catalytic spectrophotometry
Abstract: On the basis of previous studies, a catalytic spectrophotometric method using methylene blue as indicator for determination of nitrite was developed by optimizing the reaction conditions. The detection limit for nitrite was 0.07 μg/L. The linear range of the determination was 0.05~6.00 μg/mL. The developed method could be used for the determination of nitrite in water, vegetables and meat products and the determination results showed good consistency with that got through national standard determination method. The RSD of twelve determination results is less than 3.0%.
