PVP-SDS缔合行为与pH及比浓黏度的关系
Relationship between association behavior of PVP - SDS and the change of pH or reduced specific viscosity
摘要
Abstract
Methods by means of pH and reduced specific viscosity measurement were established to study polyvinylpyrrolidone (PVP)- sodium dodecylsulfate (SDS)association under various concentrations of SDS since pH and viscosity of the system are sensitive to aggregation behaviors.It is the fact that double critical concentrations of SDS in the PVP-SDS association can be characterized by both methods.The reduced specific viscosity method is more sensitive and accurate than the pH method for both the minimum and the maximum values appeared on reduced specific viscosity plots corresponding to double critical concentrations of SDS,whereas the advantage of the pH method is to support the important effect of hydrogen ion on establishment of the PVP-SDS association.关键词
