在45 ℃下,采用两相滴定法测定了4种自制高纯度十五烷基芳基磺酸盐在油砂上的吸附等温线.分别考察了表面活性剂浓度、NaCl、NaOH、NaHCO_3、正丁醇浓度及分子结构对表观吸附量的影响.结果表明,随着磺酸盐浓度的增大,吸附量先增大后有所降低.NaCl和NaOH的加入使吸附量增大,NaHCO_3及正丁醇的加入使吸附量降低,且随着芳基位置向长烷基链中间的移动,吸附量降低,受助剂的影响变小.
The isotherms and the amount of adsorption of pentadecyl aryl sulfonates with high purity synthesized in our laboratory on oil sands were determined at 45 ℃. The effects of the concentrations of surfactants, NaCl, NaOH, NaHCO_3, n-butyl alcohol and molecular structures of surfactants on pentadecyl aryl sulfonate adsorption were investigated. The experimental results show that with increasing the concentrations of the sulfonates, the absorption capacity was firstly increased, and then decreased. The absorption capacity increased with the addition of NaCl and NaOH while decreased with the addition of n-butyl alcohol and NaHCO_3. Moving the aryl from the terminal to the center of the long alkyl chain, the absorption capacity decreased, and the impact of accessory was reduced.
