| Abstract: | A novel gemini sodium nonylphenol polyoxyethylene ether sulfate(GNPES) were synthesized by gemini nonylphenol polyoxyethylene ether,sulfamic acid and 30%aqueous sodium hydroxide. Sodium nonylphenol polyoxyethylene ether sulfate(NPES) were synthesized with the same method.Critical micelle concentration(CMC) of GNPES and NPES were determined by steadystate fluorescence probe method in which pyrene was used as fluorescence probe.The experimental results showed that the CMC of GNPES was more less than that of NPES while the capability of reducing surface tension of the GNPES was almost the same as that of NPES. |
