Determination of Trace Nitrite by Catalytic Kinetic Method
A new catalytic fluorophotometric and spectrophotometric method for determining trace amounts of nitrite is proposed.The method was based on the nitrite catalysed oxida-tion of rhodamine B by potassium bromate.The detection limit for nitrite was 0.2ng/ml. The linear range of determination was 0.2～4.0 ng/ml.The method has been used to de-termine trace nitrite in rain water with satisfactory results.
