| 摘 要： | 为了探讨染料在纺织染色等领域的应用性,采用应用最为广泛的光谱法研究了阴离子表面活性剂十二烷基硫酸钠与吡罗红G的相互作用.发现当阴离子表面活性剂单体与吡罗红G形成缔合物时,荧光发生猝灭;随着表面活性剂浓度的进一步增加,表面活性剂形成的胶束与吡罗红G作用,导致出现一个新的、更强的荧光峰.同时考察了硫酸钠和尿素对二者相互作用...

| Abstract: | In order to investigate the application of dyes in the field of textile dyeing,the interaction between pyronine G(PG) and sodium dodecyl sulfate(SDS) was studied by spectral method.The results showed that the fluorescence quenching of PG appeared when it reacted with the monomer of SDS.A new stronger fluorescence peak was obtained when it reacted with the micelle of SDS.Meanwhile,the influence of Na2SO4 and(NH2)2CO on the interaction between PG and SDS was investigated.The interaction between PG and SDS bec... |
