| 摘 要： | 通常情况下，溶液中某一离子的定量分析都是在盐含量很大的情况下进行的，但油田示踪剂的分析却需要在高矿化条件下完成，特别是在原油田的产出水中，本文分析了水矿化度及其中钙镁离子对分析硝酸根离子的影响，并提出了解决这一问题的办法，形成了完整的分析方法，新方法具有分析范围宽，精密度好，准确度高的特点。

| Abstract: | Some improvements are made in quantitatively determi ning NO-3 in highly mineralized oilfield produced water by classical spectro photometric method, including ①introducing powdered zink-inert particulated ma terial in mixture as reducing agent instead of zink-salt mixture; ② adding 2 m L of ethanol to stabilize the chromophoric azo compound formed; ③ performing ab sorbance determinations at λ=526 nm in time interval 15-45 min. The range of d etection is of 0-50 mg/L and the accurancy of determinations is of 98-102.5%. |
