Quantitative Monitoring of Thulium Ions by a New Thulium Selective Polymeric Membrane Sensor

A Ho(III) potentiometric polymeric membrane sensor based on a new four dentate neutral ion carrier

“…Because the sensitivity and selectivity of any given membrane electrode is significantly related to the composition of the ion selective membrane, the nature of the solvent mediators and the used additives [36][37][38][39][40][41][42], it was decided to study such effects on the behavior of the proposed electrode. The effect of the nature and the amount of the plasticizer, the amount of ionophore and additive on the potential response of the developed Ho 3+ electrode were investigated.…”

Dysprosium selective potentiometric membrane sensor

“…We have developed some ISEs for the potentiometric determination of some ionic species [14][15][16][17][18][19][20][21][22], where polymeric membranes were prepared with increasingly selective ionophores, sensing analyte selectively.…”

Fabrication of a PVC membrane samarium(III) sensor based on N,N′,N″-tris(4-pyridyl)trimesic amide as a selectophore

“…A survey on the literature proves that there exist only a limited number of reports on selective determination of Sm 3+ ions in the presence of other rare earth elements by electrochemical method [3][4][5][6][7]. Numerous reports on the selective and sensitive PVC-membrane ISEs have recently been published [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] which made us believe another ion selective sensor could be introduced for the potentiometric determination of Sm 3+ ion based on N,N′,N″-tris(4-pyridyl)trimesic amide (TPTA) (Fig. 1).…”
