| Abstract: | A new catalytic spectrophotometric method for determination of trace nitrite has been developed. It is based on the catalysis of nitrite to the discoloring reaction of nile blue sulphate oxidized by potassium chlorate in acetic acid dium. There was lineat relationshop of AA with nitrite in the range 0?0. 3 mg/L. The detection limit was 0. 011mg/L. |
