| Abstract: | The surface properties,alkalinity and stability of dodecyltrimethylammonium hydroxide(DTAH),sodium dodecyl benzene sulfonate(SDBS) and their mixed system were studied.The results show that when the molar ratio of DTAH to SDBS was 9∶1,the mixed system was improved significantly in the capacity and efficiency of reducing the surface tension,and had good stability and strong alkalinity.The critical micelle concentration(CMC),surface tension at CMC(γCMC) and pH value of the blend system are 3.02×10-5 mol/L,28.10 mN/m and 12.46 respectively.The interaction parameter on the surface(βσ) and in micelles(βm) of DTAH/SDBS mixed system achieved-18.36,and-22.69 respectively,indicating the mixed system′s good synergism. |
