摘　　要：利用静态吸附实验研究了一种磺酸盐型双子表面活性剂TADS-10在大庆油砂和净砂上的吸附规律,并考察了时间、温度及盐、碱浓度对吸附量的影响。研究结果表明:吸附量随着温度的升高、NaCl和Na2CO3浓度的增大而逐渐增加后趋于平稳,随着表面活性剂浓度的增加呈现先增大后降低的趋势,并且吸附热力学研究表明,双子表面活性剂在油砂上的吸附等温线服从Langmuir等温方程。The static adsorption performance of TADS-10 on oil and oil-free sand from the Daqing oilfield was studied and the influence of adsorption time,adsorption temperature,concentrations of NaCl,and Na2 CO3,on the efficiency of adsorption were investigated.The experimental results show that with the increase of temperature and addition of NaCl and Na2 CO3 the adsorption capacity initially increased,with an increase in the concentrations of the sulfonates on oil sand the adsorption capacity initially increased then reduced.Adsorption thermodynamic re-sults show that the adsorption of Gemini surfactant onto oil sand could be well described by the Langmuir isotherm.
