摘　　要：采用高效液相色谱法对聚驱采油废水中残留的聚丙烯酰胺进行定量分析。色谱条件为Shim-pack CLCODS色谱柱,流动相为甲醇∶水(90∶10,体积比),含0.05 mol/L氯化铵缓冲溶液,检测波长210 nm,流速0.8 mL/min,柱温40℃,进样体积2μL。在该条件下,测定聚丙烯酰胺标准溶液及水样,根据标准曲线对水样中聚丙烯酰胺进行定量分析,并计算加标回收率及精确度,为聚驱采油废水的处理提供有效的数据支持。Adopting HPLC to analyze the quantity of residual hydrolyzed polyacrylamide（ PAM） in EOR oil-bearing wastewater. Chromatographic conditions： Shim-pack CLC-ODS,the mobile phase was methanol and water 90 ∶ 10（ V / V）,containing 0. 05 mol / L ammonium chloride buffer solution,the detection wavelength was 210 nm,the flow rate was 0. 8 mL / min,column temperature was 40 ℃,and injection volume was 2 μL. Under this condition,determination of PAM standard solutions and wastewater sample. According to standard curve of PAM,used it for quantitative of PAM in wastewater sample,the recovery rate and precision were calculated. This method could provide effective data support for treating of EOR oilbearing wastewater.
