SMA,SSMA与醇醚硫酸盐相互作用的荧光研究

Study on the Interaction of Copolymers SMA and SSMA with Polyoxyethylene Alkyl Ether Surfactant by Fluorescent Method

摘要: 利用荧光光谱法结合通常的表面张力法，研究了水溶性苯乙烯－马来酸酐共聚物及磺化苯乙烯－马来酸酐共聚物和烷基醇聚氧乙烯醚硫酸盐之间的相互作用。结果表明，两者相互作用效果与表面活性剂结彩名环氧乙烷加成数及成盐金属离子性质有关，即随环氧乙烷加成数的增加其相互作用增强，成盐离子ＮＨ４＾＋比Ｎａ＾＋（ＡＥＳ）的相互作用弱。

Abstract: The combination of fluorescence spectroscopy and traditional surface tension method is used to investigate the interaction of hydrosoluble copolymer SMA and SSMA with polyoxyethylene alkyl ether surfactant.Results show that the interaction effect is related to the adduct number of polyoxyethylene in surfactants and the properties of salt forming metallic ions.Increasing adduct number of polyoxyethylene strengthens the interaction.The salt forming NH + 4 ion is weaker than Na + ion in the interaction.
