摘要
研究了测定废水中痕量亚硝酸盐的对氨基苯磺酸－８－羟基喹啉光度法。该方法的灵敏度高，选择性好，试剂溶液稳定，在０～２４μｇ／５０ｍＬ范围内服从比耳定律。
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.
