A New Lead(II)-Selective PVC-Coated Graphite Rod Electrode Based on a Schiff Base Complex

Ion Recognition: Application of Symmetric and Asymmetric Schiff Bases and Their Complexes for the Fabrication of Cationic and Anionic Membrane Sensors to Determine Ions in Real Samples

“…Arida and co-workers designed a Pb 2+ -selective PVC-coated graphite rod electrode, based on a Schiff base complex. It presented a linear Nernstian response with a cationic calibration slope of 30.0 ± 0.2 mV decade -1 [13]. The next two studies of the same year were conducted by the same authors, Ardakani et al In the first paper, they described a highly selective Pb 2+ coated-wire electrode, capable of providing lead determination in mineral rocks and wastewater [14].…”

Polymeric Lead(II)-selective Electrode Based on N,N'-Bis-thiophen-2-ylmethylene-pyridine-2,6-diamine as an Ion Carrier

“…The resulting Schiff base complexes have attracted increasing attention in the area of ionic binding and selectivity due to their unique properties and reactivity. Recently, many works were reported about their complex formation equilibria in solution 1,2 and also about the use of Schiff base as an ion carrier in ISEs for determining metal ions such as aluminium (III), 3 chromium(III), 4 cobalt(II), 5 copper(II), [6][7][8][9][10][11][12] gadolinium (III), 13 lead(II), [14][15][16][17][18][19][20] mercury(II), 21,22 nickel(II), 23 silver(I), [24][25][26] yttrium(III). 27 Many ionophores with high selectivity for specific metal ions have been developed for the potentiometric sensors for the determination of the target metal ions.…”

A Selective Membrane Electrode for Lanthanum(III) Ion Based on a Hexaaza Macrocycle Derivative as Ionophore

“…In recent decades, many intensive studies on the design and synthesis of highly selective ionophores as sensory molecules for ion-selective electrodes have been reported. [1][2][3][4] In spite of successful progress in the design of highly selective ionophores for various metal ions, there are only a limited number of reports on the development of highly selective ionophores for lanthanum. [5][6][7][8][9][10][11][12][13][14][15][16][17] Macrocyclic complexes of lanthanides [18][19][20] have generated a growing interest because of their potential applications in biology, 21 material science and in chemical processes.…”
