用移动相中含有磷酸二氢钠的反相高效液相色谱法分析了烷基磺酸钠和烷基苯磺酸钠。对前者用电导检测器直接进行检测(无抑制柱),后者用紫外检测器检测。对几种商品十二烷基苯磺酸钠的组分和微乳液中十二烷基磺酸钠的含量进行了测定。得到了满意的结果。
The sodium alkyl sulfonates and sodium alkyl benzene sulfonates were analyzed by RP-HPLC with mobile phase of sodium dihydrogen phosphate. The former is detected directly with a conductivity detector (no suppression column), which is detected with a UV detector. Several components of sodium dodecyl benzene sulfonate and the content of sodium dodecyl sulfate in the microemulsion were determined. Have been satisfied with the results.
