摘要/Abstract

摘要： 介绍了以二聚壬基酚聚氧乙烯醚,氨基磺酸,氢氧化钠为原料,合成二聚壬基酚聚氧乙烯醚硫酸钠(GNPES),同样方法合成壬基酚聚氧乙烯醚硫酸钠(NPES),以芘为荧光探针,用稳态荧光探针法测定了合成的GNPES和NPES的临界胶束浓度。

关键词: 稳态荧光猝灭, 临界胶束浓度, 二聚壬基酚聚氧乙烯醚硫酸钠

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.

Key words: steady-state fluorescence quenching, critical micelle concentration, gemini sodium nonylphenol polyoxyethylene ether sulfate
