| 摘 要： | 采用Klett光电比色计考察了C14-16 α-烯基磺酸钠和烷基二苯醚双磺酸盐(C14-16AOS/Dowfax8390)复配体系的耐盐(NaCl)能力,并考察了NaCl质量浓度对C14-16AOS/Dowfax8390复配体系与癸烷间的界面张力的影响。结果表明:随着Dowfax8390质量浓度的增加,复配体系的耐盐能力增加;C14-16AOS与癸烷间的动态界面张力迅速达到平衡。随着NaCl质量浓度的增加,Dowfax8390与癸烷间的动态界面张力达到平衡的时间明显缩短。组成为m(C14-16 AOS)∶m(Dowfax8390)=5∶5的复配体系与癸烷之间的界面张力比组成为8∶2的高,但低于单一的Dowfax8390与癸烷之间的界面张力,而与单一的C14-16AOS与癸烷之间的界面张力相近。复配体系与癸烷间的界面张力随NaCl质量浓度的增加而降低;在NaCl质量浓度相同条件下,复配体系中Dowfax8390含量的增加导致复配体系与癸烷间的界面张力升高。

| Abstract: | Salt tolerance of blend system of sodium C14-16 alpha-olefin sulfonate and sodium alkyldiphenyl oxide disulfonate(C14-16AOS/Dowfax8390) was investigated by Klett photoelectric colorimeter.Effect of NaCl mass concentration on interfacial tension of the blend system was studied.Results showed that,the salt tolerance of the blend system will be enhanced with increasing of Dowfax8390 mass concentration;while dynamic interfacial tension between C14-16AOS aqueous solution and decane can reach equilibrium quickly.... |
