| 摘 要： | 油田采出水经光电催化氧化法处理后，有机物和油被充分降解，用离子色谱法测定 NO3-、PO3-4，5次测定结果的 RSD为3．1％～5．8％。该方法测定出水中 NO3-、PO3-4质量浓度可代表除油处理后原水中总氮、总磷质量浓度，与分光光度法测定原水中总磷、总氮的结果相比，重现性好、耗时少。

| Abstract: | Oilfield produced water was treated by photo catalytic oxidation,in which organic matter and oil was fully degradated,NO-3 and PO3-4 were determined by ion chromatography.The results showed that the RSDs were 3.1% and 5.8% respectively by 5 times determinations.Ion chromatography method for determination of NO-3 and PO3-4 concentration could represent concentration of total nitrogen and total phosphorus in raw water.Compared with spectrophotometric method,it showed good reproducibility,less time consuming. |
