Title: Spectrophotometric Determination of Nitrite with Methyl Orange
Abstract: A new method for determination of NO -_2 was established based on the catalytic effect of NO -_2 on oxidation of methyl orange by potassium bromate.The linear range is 0.1—0.4μg/mL with detection limit of 8.1×10 -2 μg/mL.The method was applied to determine nitrite in water and fresh vegetables with satisfactory results.
