Abstract
The development of a phosphate sensitive electrode based on a heterogeneous (Ce-O-Ce) (HPO4)3·H2O / PVC membrane is described. At a certain salt / PVC - mixture ratio an electrode for H2PO4 − with a slope of -50 mV/activity decade (AD) and a detection limit of approximately 20 ppm H2PO4 − is obtained. the selectivity coefficients for the interfering ions So4 2−, cl−, NO3 −Keywords
