Sensor for Silver(I) Ion Based on Schiff-base-p-tertbutylcalix[4]arene

Abstract

Abstract:The preparation of polymer membrane selective to silver ion and its application to ion-selective electrode is reported here. PVC membrane contain silver-selective calix

Novel Silver(I) Ion Selective PVC Membrane Electrode Based on the Schiff Base (N2E,N2'E)-N2,N2'-Bis(Thiophen-2-ylmethylene)-1,1'-Binaphthyl-2,2'-Diamine

“…The potentiometric selectivity coefficients measure the response of the electrode for the primary ion in the presence of foreign ions. 28 The results for the Schiff base (m-2) are shown in Table 3. A perusal of the coefficients reveals that the sensor was selective to silver ions over the other cations.…”

Polymeric Membrane Silver-ion Selective Electrodes Based on Schiff Base N,N'-Bis(pyridin-2-ylmethylene)benzene-1,2-diamine

“…The potentiometric selectivity coefficients measure the response of the electrode for the primary ion in the presence of foreign ions. 22 The selectivity coefficients of the electrodes were determined by a method developed by Bakker. 27 The result for Schiff base BPBD (m3) is shown in Fig.…”

“…[9][10][11][12][13][14][15] Different number of the mycrocyclic ring or replacing atoms by nitrogen atoms in the mycrocyclic ring, the affinity will be expected to be toward heavy or transition metal cations. 16 On the other hand, by using aza-macro compounds as neutral carriers in PVC membranes, highly selective electrodes for heavy 17 and transition metal 18 cations and silver ions [19][20][21][22] have been developed. Many Schiff bases have been studied as carriers for various metal ion-selective electrodes.…”

Manganese(II) Ion-Selective Membrane Electrode Based on N-(2-picolinamido ethyl)-Picolinamide as Neutral Carrier

“…So, they form one of the most important groups of chemical sensors. [1][2][3][4][5][6][7][8][9][10] After extensive efforts some of the commercial sensors are available for alkali, alkaline earth metals, halides, nitrates, etc. Efforts are required to develop ion-selective electrodes for heavy metal ions, which are toxic in very low concentration.…”
