摘　　要：研究了十氢萘溶液中载体γ-Al2O3、SiO2与聚苯乙烯的作用过程,探讨了吸附温度、聚苯乙烯初始浓度、吸附时间对吸附的影响。结果表明,载体对聚苯乙烯的吸附量随温度的升高而增大,随聚苯乙烯初始浓度的增大而先增大后变小,随时间的延长而增大。聚苯乙烯在吸附过程中经历构象变化,最后在载体上呈现拉伸状椭圆形分子结构。Studied the action process of γ-Al2O3and SiO2carriers in decahydronaphthalene solution and polystyrene. Effect of adsorption temperature,initial polystyrene concentration and adsorption time on adsorption were investigated. The results indicated that polystyrene adsorption capacity of carriers were increased with the increment of temperature and adsorption time,increased at first then decreased with increase of initial polystyrene concentration. Polystyrene molecules underwent conformational rearrangements to form a stretched ellipsoidal shape on the surface of carriers.
