|
摘要
以三氯氧磷、1,3-丙二醇、乙二醇单丁醚为原料制备磷酸盐型双子(Gemini)阴离子表面活性剂,并对其结构进行HNMR证实,同时对其溶液表/界面活性和土壤重金属离子去除进行初步研究。表界面活性研究表明:该表面活性剂具有较高的表面活性和界面活性,CMC为0. 002 5 mmol/L,γCMC为24. 3 m N/m,当浓度为1 mmol/L时,最低界面张力为0. 85 m N/m。土壤重金属去除研究表明:该表面活性剂对Pb2+和Cr3+具有良好的去除效果,与清水相比分别提高了31倍和7倍。
In this paper,a phosphate anionic surfactant( Gemini) was prepared With phosphoryl trichloride,1,3-propylene glycol and ethylene glycol monobutylether as raw material,and its structure was confirmed by HNMR. The results show that the synthesized surfactants was higher surface activity and interfacial activity,CMC was 0. 002 5 mmol/L,γCMCwas 24. 3 m N/m,and the lowest interfacial tension was 0. 85 m N/m when the concentration was 1 mmol/L. The study of heavy metals removal of contaminated soil showed this surfactant had a good removal effects on Pb2 +and Cr3 +,which was 31 times and 7 times higher than that of clean water,respectively.
