| Abstract: | A catalytic spectrophotometric method is proposed for determining trace amounts of nitrite. The method was based on the nitrite catalysed oxidation of light green SF by potassium bromate, with the results of decoloration. The range of determination was 0. 05-20 ng/mL for nitrite. The method has been used to determine trace nitrite in water with satisfactory results. |
