| 摘 要： | 采用向十三烷基苯磺酸钠（STBS）和非离子表面活性剂辛基酚聚氧乙烯醚（OP-10）二元复配溶液中添加β-环糊精（β-CD）的方法，降低STBS和OP-10之间定量检测时的相互干扰。实验结果表明：添加β-CD时，可提高STBS的检测准确性，降低STBS对OP-10的检测干扰；在二元复配溶液中，STBS和OP-10的方法回收率分别在100.8%~102.0%，97.4%~102.2%之间，检测误差分别在2.0%和2.6%以内；Cl-，SO42-，Na+，Ca2+的存在对二元复配溶液中STBS和OP-10的检测干扰可忽略；将该方法应用于地层水水样中，仍可准确定量分析STBS和OP-10的含量。

| Abstract: | A new method was developed for reducing the interaction between sodium tridecylbenzenesulfonate (STBS) and nonion surfactant octaphenyl polyoxyethyiene (OP-10) in their quantitative analysis by adding β-cyclodextrin (β-CD) into their complex aqueous solution. The experimental results indicate that：Adding β-CD can improve the determination precision of STBS and reduce its effect on the detection of OP-10；The recovery rates of STBS and OP-10 are 100.8%-102.0% and 97.4%-102.2% respectively,and the detection errors are within 2.0% and 2.6% respectively；The effects of Cl-,SO42-,Na+,Ca2+ on the quantitative determination of STBS or OP-10 can be ignored；The method can be applied to the quantitative analysis of STBS and OP-10 in formation water. |
