本文报道了高压液相色谱法(HPLC)测定废水、河水中阳离子表面活性剂。该方法以直链烷基苯磺酸盐(LAS)作为络合剂,用二氯甲烷萃取二脂二甲基氯化铵(ditallow dimethyl ammonium chloride DTDMAC)阳离子表面活性剂,然后由HPLC—电导检测器进行分离、定量。 HPLC-装置、操作条件和定量: 色谱系统包括:配有50μl环状进样器的Varian 5000型液相色谱仪,Wescan电导池和检测器,Whatman Partisil PAC 10柱(氰氨基键合相)和含有Whatman Co-Pell PAC防护柱。以氯仿:甲醇(92:8)混合液为流动
This paper reports the determination of cationic surfactants in waste water and river water by high pressure liquid chromatography (HPLC). The method uses linear alkylbenzene sulfonate (LAS) as a complexing agent, ditallow dimethyl ammonium chloride (DTDMAC) cationic surfactant is extracted with dichloromethane, and then detected by HPLC-conductivity detection Device separation, quantitative. HPLC-Apparatus, Operating Conditions and Quantification: The chromatography system consisted of a Varian Model 5000 liquid chromatograph equipped with a 50 μl loop sampler, a Wescan cell and detector, a Whatman Partisil PAC 10 column (Cyanamid bonded phase) and Contains Whatman Co-Pell PAC guard column. To chloroform: methanol (92: 8) mixture for the flow
