摘要： 将聚苯乙烯(PS)和乙基纤维素(EC)溶于CH2Cl2中,利用水中干燥法制备PS-EC复合膜微胶囊。当复合膜的微孔中含有磷酸三丁酯(TBP)时,微胶囊膜对Cr2O72-具有传输功能。芯材采用高浓度NaOH时,可使Cr2O72-逆浓差传输。研究了PS和EC的比例、微胶囊粒径、NaOH浓度及TBP含量对传输的影响。在适当条件下,10min内Cr2O72-的浓度由1×10-4mol/L降至1×10-7mol/L以下。

Abstract: PS(polystyrene) and EC(ethyl cellulose) were dissolved with CH2Cl2, and PS-ECmicrocapsule was prepared by means of drying in water.When the tiny pores of the film contain TBP(tributyl phosphate), it shows the function transferring.Cr2O72- We investigated the effect of proportions of PSand EC, the radii of microcapsule, and the concentrations of NaOHand TBP.The results show that the concentration of was dropped down in l0min from 1×10-4 mol/Lto 1×10-7mol/Lunder the appropriate conditions.
