Cu(II) Ion- Selective Membrane Electrode Based on bis(N-salicylidene-3,3'-diamino diphenyl) sulfone
In order to study the Cu(II) ion selective electrode, an optimized membrane was prepared by mixing of 30 mg of PVC powdered, 5 mg of considered ionophore, 60 mg of plasticizer and 5 mg of additive. The sensor showed a near Nernstian response for Cu(II) ions over a concentration range from 1.0×0-6 –1.0×0-2 M with a slope of 28.90.5 mV per concentration decade with a working pH range of 3.5-6.3. ...
متن کاملSn (II) Ion- Selective Membrane Electrode based on Dibenzo-18-Crown-6
We found that dibenzo-18-crown-6 (DB18C6) can be used as an ionophore to make a tin (II)-ionselectivemembrane electrode. The electrode exhibits a near Nernstian response for Sn2+ ions over aconcentration range from 1.0× 10-6 – 1.0× 10-2 M with a slope of 27.5 ± 0.6 mV per concentration decadein an acidic solution (pH=1). The limit of detection was 8.0× 10-7 M. It has a response time of < 20s an...
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...
