| Abstract: | new catalytic spectrophotometric method for determining trace NO2-has been described.The method is based on the catalytic oxidation of malachite green by potassium bromate in the solution of dilute phosphoric acid. The linear range for determination is 450ng/25ml for nitrite. The method is suitable for the determination of nitrite in water samples and vegetables. |
