Phase Diagram Prediction Of Recycling Aqueous Two-phase Systems Formed By A Light-sensitive Copolymer And Dextran

摘要

Our Laboratory has synthesized a novel light-sensitive and recycling copolymer P_(NBC). The P_(NBC) copolymer could form recycling aqueous two-phase systems with Dextran. Recycling aqueous two-phase systems have important application in bioseparation engineering. Phase diagram prediction of the novel aqueous two-phase systems also is an important aspect in engineering. This article applied the Cabezas model and effective excluded volume (EEV) model to the experimental data of light-sensitive recycling aqueous two-phase systems. It has been found that the EEV model could consist with experimental data very well. The maximum absolute error and average absolute error is 0.81% (wt%) and 0.23% (wt%), respectively.
