5,10,15,20-tetraphenylporphyrin (TPP) and 5,10,15,20-tetra(4-methylphenyl) porphyrin (TMPP) have been explored as electroactive materials for preparing poly(vinyl chloride) (PVC) based membrane sensors selective to Ni 2+ . The membrane incorporating TMPP, sodium tetraphenylborate and a solvent mediator (dibutylphthalate) in PVC in the ratio (7 : 35 : 4 : 54) gave the best results, exhibiting...
