Increase of vanillin partitioning using aqueous two phase system with promising nanoparticles.

ABSTRACT: The distinct features of ATPSs (aqueous two-phase systems) have made it possible to promote the extraction efficiency of biomolecules. The purpose of this study is to discover an appropriate nanoparticle to design an economical optimal separation process, and to understand the underlying molecular mechanism which allows the partitioning of vanillin as a phenolic compound using nanoparticle-based ATPSs. To this aim, the capabilities of several different nanoparticles were investigated as additives for boosting the partition coefficient of vanillin in two different ATPSs made up of polyethylene glycol and sodium sulfate/polyethylene glycol and dextran. Also, in an attempt to explain the salting-out effect, the NRTL (Non-random Two Liquid) thermodynamic model was applied. The impact of very s
