摘要
为了认识阳离子Gemin表面活性剂(NNMB)的吸附特性,从时间、液固比、质量浓度、温度以及pH值等方面系统地研究了NNMB在净砂上的静态吸附性能。实验表明:NNMB的吸附量随着电解质浓度及离子强度增加而增大,在碱性溶液中的吸附主要是靠静电作用。这为进一步探求有效抑制NNMB吸附损失的方法和研究其在驱油中的应用打下了基础。
The effect of time, liquid/solid ratio, quality concentration, temperature and pH value on the ultraviolet visible prismatic luminosity method of NNMB surfactant is studied; the results show that the adsorption quantity of NNMB increases with the increase of electrolyte concentration and ion intensity, the adsorption loss in alkali solution is mainly electrostatic action. The results provide a basis for the method of effectively controlling NNMB Gemini surfactant adsorption loss and further application of the cationic gemini surfactant in oil displacement.
