Manganese (M-selective PVC membrane electrode based on N-(2- picolinamido ethyl)-Picolinamide as ionophore
In this research, a PVC membrane electrode for Manganese (II) ions based on N-(2-Picolinamidoethyl)Picolinamide as neutral carrier was prepared. The electrode exhibits a Nemstian responseover Mn(II) concentration range of (1.0 x10-5 t01.0 X 10-1M) with a slope of 29.3±0.5 mV perdecade of concentration with a working pH range of 4.0-9.0. It has a fast response time (

متن کاملFe (II) Ion-Selective Membrane Electrode based onTetra-Phenyl Porphyrin in PVC Matrix
Fe2+ ion-selective membrane sensor has been fabricated from polyvinyl chloride (PVC) matrixmembrane containing neutral carrier tetra phenyl porphyrin (TPP) ionophore. The addition ofsodium tetraphenylborate (NaTPB) and the plasticizer DBP has been found to substantiallyimprove the performance of the sensor. The best performance was obtained with the sensor havinga membrane of composition of TPP...
