| 摘 要： | 采用高速离心分离结合0.45μm孔径滤膜抽滤技术,处理油田地质钻探泥浆样品。用背景抑制电导离子色谱法对泥浆浸取液中Cl-等主要阴离子进行分析。代表性样品中高Cl-和低SO24-两种阴离子含量分别为1656和804mg·L-1;相对标准偏差(RSD)(n=6)分别为0.52%和0.62%;回收率分别为102.2%和105.2%。与传统化学法相比,该方法具有测试简便,分析周期短、准确性高的特点。 |

| Abstract: | The slurry was dealt with by dilution, centrifugation （8000 r·min^-1） and filtration （-0.1MPa vacuum and 0.45μm filter membrane ）. An suppressed conductivity ion chromatography method was used to determine main anions in the aqueous extract of the slurry. The concentrations of Cl^- and SO4^2- were 1656 and 804mg·L^-1 with RSD （n=6） 0.52% and 0.62%, and recoveries of 102.2% and 105.2% respectively. The method is easy to handle with characteristics accurate results and shorter analytical duration comparing to traditional chemical way. |
