摘要：

Aminated poly(vinyl chloride)s (PVCs) and neutral carriers can produce nearly ideal pH sensors. However, they can show Donnan exclusion failure in low pH bathing solutions. These pH-sensitive PVC membranes illustrate a new dimension, not found for other mobile neutral-carrier-based sensors, i.e., Donnan failure produces fixed positive sites that create a nearly ideal anion sensor. The modification of Donnan theory is derived and illustrated using carrier-based and aminated-PVC-based sensors.
