针对AP-P4/SDBS聚表二元体系,选用不同浓度配方的聚表体系,在石英砂上展开静态吸附和动态滞留实验,研究聚表体系中各组分的吸附规律,考察了浓度、温度、矿化度对组分的吸附影响。结果表明,聚表二元体系中各组分在石英砂上的吸附符合Langmuir吸附模式,其中,SDBS表现为双分子层吸附、AP-P4表现为单分子层吸附特质。AP-P4与SDBS存在竞争吸附关系,SDBS的吸附量是AP-P4的20多倍。温度和矿化度升高,SDBS的吸附量增大。聚表二元体系中SDBS的动态滞留量小于其静态吸附量,而AP-P4的动态滞留量大于其静态吸附量。
According to the AP-P4 / SDBS multi-collection binary system, the static adsorption and dynamic retention experiments were carried out on quartz sand to study the adsorption rules of each component in the poly-collection system. The effects of concentration, temperature, Effect of salinity on component adsorption. The results show that the adsorption of various components on quartz sand complies with the Langmuir adsorption model. Among them, SDBS shows bilayer adsorption and AP-P4 shows monolayer adsorption. AP-P4 and SDBS exist competitive adsorption relationship, SDBS adsorption capacity is AP-P4 of 20 times. Temperature and salinity increased, SDBS adsorption increased. The dynamic retention of SDBS in the binary table of aggregation is less than its static adsorption, while the dynamic retention of AP-P4 is greater than its static adsorption.
