| Abstract: | An optimum condition of spectrophotometric determination of trace nitrite in waste water with p aminobenzene sulfonic acid 8 hydroxyquinoline is dealt with.This method has high sensitivity and fairly good selectivity,and the reagent solution is stable. Beers law is obeyed in the range of 0～24μg/50ml. |
