Samarium(III)-PVC-Membrane Sensor Based on Ethoxy-1-ethoxycarbonyl-1,2-dihydroquinoline

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

“…The effect of membrane ingredients on the properties of the membrane electrodes, including the effect of the plasticizer, the plasticizer/PVC ratio, the nature and amount of ionophore, and especially, the nature and amount of the additives used, have been reported to significantly influence the behavior of ion-selective electrodes [43][44][45][46][47]. These were hence studied for the TPTA-based Sm 3+ -selective membrane and the results are given in Table 1.…”

“…Due to this fact that the nature of the used plasticizer, influencing the dielectric constant of the membrane phase, the mobility of the ionophore molecules, and the state of ligand [43][44][45][46][47], affects the properties of the ISE membranes; i.e. the selectivity, working concentration range, and response time of the membrane electrode, for different solvent mediators (NB, AP, BA, and DBP) were tested.…”

Construction of Eu3+ Ion‐Selective Electrode Based on 1,2‐Diaminopropane‐N,N,N′,N′‐tetraacetic acid

“…A Pyrex tube (3-5 mm o.d. on top) was dipped into the mixture for about 5s, so that a transparent membrane of about 0.3 mm thickness was formed [19][20][21][22][23][24][25][26][27] . The tube was pulled out from the mixture and kept at room temperature for 12 h. The tube was then filled with an internal solution (1.0×10 -3 M EuCl 3 ).…”

A lutetium pvc membrane sensor based on (2-oxo-1,2-diphenylethylidene)-n-phenylhydrazinecarbothioamide

“…[22][23][24][25][26][27][28][29][30][31][32][33][34] The tube, now having a layer of the membrane on the tip were next kept at room temperature for 12 h before being filled with an internal filling solution (1.0×10 -3 mol L -1 of the target ion) and conditioned for 24 h in a 1.0×10 -2 mol L -1 solution of the target ion. To do this, the tips of the tubes were dipped into the mixture for a short time.…”
