Stabilization of supported liquid membranes by gelation with PVC [PDF]
Journal of Applied Polymer Science, 1997 This article describes the gelation by PVC of supported liquid membranes (SLMs) for nitrate removal using a quaternary ammonium salt as carrier. Untreated SLMs with this carrier are very unstable. To improve their stability, the LM-phase was gelled with polyvinyl chloride as gel-forming polymer. Both homogeneous gelations of the LM-phase as well as the

PVC Membrane Sensors for Potentiometric Determination of Acebutolol [PDF]
Sensors, 2007 The construction and general performance characteristics of two novelpotentiometric membrane sensors responsive to the acebutolol are described. Thesensors are based on the use of ion-association complexes of acebutolol (AC) withtetraphenylborate(TPB) (I) and phosphomolybdate(PM) (II) as exchange sites in a PVCmatrix.

The Study on a PVC Membrane Electrode for Gemfibrozil.
Biological and Pharmaceutical Bulletin, 2002 In this paper, a poly(vinyl chloride) (PVC) membrane electrode is prepared for gemfibrozil, 2, 2-dimethyl-5-(2,5-xylyloxy) valeric acid, based on its ion pair complexes with hexadecyltrioctyl ammonium iodide (HTOA). The membrane composition of the electrode was optimized by using the sequential level elimination method for orthogonal experimental ...
