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。
Oilfield produced water was treated by photo catalytic oxidation,in which organic matter an d oil was fully degradated,NO3-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 NO3-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.
