摘要：

A rapid,simple,sensetive and selective method for the determination of trace amounts of nitrite ion(30-800 ng/ml) is developed. It depends on the reaction of nitrite with Neutral Red.The reaction is monitored spectrophotometrically by measuring the decrease in absorbance at 530 nm by a fixed time method.The limit of detection is 14 ng/ml. The method is used for the determination of nitrite ion in waste water.
