Fabrication of a Praseodymium(III) PVC-Membrane Sensor Based on N′¹,N′²-Bis(2-oxo-1,2-diphenylethylidene) ethanedihydrazide

Application of N‐Quinoline‐2‐carboxamido‐8‐aminoquinoline in Fabrication of a Ho(III)‐PVC Membrane Sensor

“…The solvent was then evaporated slowly, until an oily concentrated mixture was obtained. A Pyrex tube (3-5 mm in top) was dipped into the oily mixture for about 5 s, so that a transparent film of about 0.3 mm thickness was formed [33][34][35][36][37][38][39][40][41][42][43] . Afterwards, the tube was removed from the mixture, kept at the room temperature for about 12 h and filled with the internal filling solution (1.0×10 −3 M of HoCl 3 ).…”

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

“…In comparison, potentiometric ion selective sensors offer advantages of low cost, portability, selectivity, and simple operatory. They also provide an analysis method without destruction of sample [8][9][10][11].…”

Gadolinium(III) Ion‐Selective Electrode Based on 3‐Methyl‐1H‐1,2,4‐triazole‐5‐thiol

“…Many techniques have been used for determination of Gd which most of them have been spectroscopic methods such as inductively coupled Plasma-mass spectrometry (ICP-MS), atomic emission spectroscopy, electron spin resonance, laser-based multi step resonance ionization, phosphorescence opto-sensing, high-resolutionˆI3-spectroscopy, timeresolved fluorimetry, spectrophotofluorimetric determination, quenching of gadolinium fluorescence and some nucleic methods. Recently, several greatly selective and sensitive PVC-membrane ion-selective electrodes for various metal ions have been reported [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] . This research focuses on the introduction of a highly Gd(IIII)-selective sensor based on 3-methyl-1H-1,2,4-triazole-5-thiol (MTH) (Figure 1), as an ionophore for determination of Gd(III) ion concentration.…”
