研究了刚果红溶液的光化学性质， 利用 Ｎ Ｏ－３ 对刚果红溶液在紫外光作用下发生的褪色反应的催化作用， 建立了测定痕量 Ｎ Ｏ－３ 的新方法， 其线性范围为０ ～０８ ｍｇ／ Ｌ。对自来水样品进行加入回收实验， 相对标准偏差在２５ ％ 以下， 回收率在９９０ ％ ～９９４ ％ 之间
The photochemical properties of Congo red solution were studied. The catalytic effect of N O-3 on the fading reaction of Congo red solution under ultraviolet light was studied. A new method for the determination of trace N O-3 was established. The linear range was 0 ~ 08 mg / L. Tap water samples were added to the recovery experiment, the relative standard deviation of 2 5%, the recovery was 99 0% ~ 99 4%
