| Abstract: | The catalytic effect of No2-on oxidation of methylene blue by potassium bromate was studied and a new method for determination of No2 -based on this was reported. The linear range for determination of No2 -is 0.1~0.6 ug/ml with detection limit of 0.15 ug/ml. The method was applied to determine nitrite in water and vegetables with satisfactory results. |
