| 摘 要： | 用流动微量量热法研究了十二烷基硫酸钠(SDDS)和十二碳羧酸钠(SL)在克拉玛依油田九区和乌尔禾区油砂上的吸附,简要地计论了吸附机理。所得实验结果表明,SL 在油砂上的吸附强度比 SDDS 的要大,在相当低的浓度下即可迟到饱和吸附。

| Abstract: | The adsorption of sodium dodecyl sulfate (SDDS) and sodium layrate (SL) on oily sands from two districts,XO and WO,Karamai Oil Fieid,is investigated experimentally by means era newly established flow microcalorimeter and discussed.The adsorption on these oily sands is physical in nature and the data of adsorption enthalpies,though being scattering demonstate similar surface-chemical character of the two kinds of oily sands. The isoterms of enthalpies of SDDS adsorption onto and desorption from oily sands are overlapped entirely or in some extent in low concentrations (below its CMC) and be- come departed from each other above its CMC.For SL the same is observed besides of that the experimental points for adsorption and desorption are highly s(?)attering and mixed. |
