Nitrite-sensitive liquid membrane electrodes based on metalloporphyrin derivatives

Highly Selective Thiocyanate Electrode Based on Bis-[N-(2-hydroxyethyl)salicylaldimino]copper(II) Complex as a Neutral Carrier

“…Recently, ever more attention has been focused on electrodes using plasticized poly(vinyl chloride) (PVC) membranes incorporating derivatives of vitamin B12, Co(III), Sn(IV), Mn(II) and Mo(IV) porphyrin complexes, which have shown a remarkable deviation from the Hofmeister pattern. [3][4][5][6][7][8][9] This kind of electrode made it possible to detect ion after perchlorate directly and expediently. It is very important to monitor and determine thiocyanate in spin and electroplate industrial and environment protection, since SCN -can harm humans and aquatic life.…”

Dibenzocyclamnickel(II) as Ionophore in PVC-Matrix for Ni2+-Selective Sensor

“…The R 4 Bzo 2 [14]aneN 4 type dibenzocyclam derivatives due to their flat geometry are also expected to form stacks in solid lattices and are also expected to possess good miscibility with the PVC matrix for the rapid exchange of metal ions [23]. Consequently, they can be used as active material in the membrane phase to prepare selective electrode for a particular metal ion [24][25][26]. In this paper, results on the PVC matrix membrane sensor incorporating ([Ni(Me 4 Bzo 2 [14]ane N 4 )]Cl 2 ) ionophore for the determination of nickel in aqueous solutions have been presented and discussed.…”

PVC Based Selective Sensors for Ni2+ Ions Using Carboxylated and Methylated Porphine

“…The use of Porphines as sensor material for membrane has been reported recently [11][12][13]. Porphines are aza, cyclic molecules capable of forming electron rich interior cavities in which metal cation is encapsulated through ion-dipole interactions as two pyrrolenine nitrogens are capable of accepting two protons and two -NH groups capable of losing equal number of protons.…”
