摘要：

The pH difference existing between phases of poly(ethylene glycol)-potassium phosphate aqueous two-phase systems is shown to affect the partition coefficients of charged solutes. This effect is modeled and experimental results agree with the behavior predicted. © 1991, Taylor & Francis Group, LLC. All rights reserved.
