摘要
应用紫外-可见分光光谱法研究了黄色双偶氮类分散染料与不同种类表面活性剂及无机盐的相互作用。结果表明:表面活性剂使黄色分散染料最大吸收波长红移,且对其有分散、增溶作用;十二烷基磺酸钠促进染料分散、增溶作用最好;无机盐对染料的最大吸收峰没有影响;NaCl对染料的分散起抑制作用,Na2SO4在低浓度时促进染料聚集,当浓度达到一定程度时,Na2SO4对染料溶液的分散起促进作用,但这种促进作用明显小于表面活性剂。
Interactions between a disazo disperse yellow and different surfactants or inorganic salts in aqueous solution were studied by using UV-Vis absorption spectra. The results showed that surfactants let the maximum absorption wavelength of dye increased; surfac- rants had disperse, solubility effects on dye, sodium dodecyl sultbnate was the most significant surfactant; inorganic salt had no effect on maximum absorption wavelength of dye; NaC1 has inhibition effect on dye, Na^S04 has same effect in low concentration, but it has disperse effect on dye in a certain concentration although the effect was obviously less than that of surfactants.
