Selective ion separation via capacitive deionization (CDI) is of relevance because its environmental and industrial applications in water purification softening, heavy metal removal, resource recovery. Conventionally, carbon electrodes ion-selective membranes have been used for selective removal anions cations. In this study, we engineered a CDI cell with two identical NiHCF electrodes, separat...

The local microenvironment at the electrode-electrolyte interface plays an important role in electrocatalytic performance. Herein, we investigate effect of acid electrolyte anion identity on oxygen reduction reaction (ORR) activity and selectivity smooth Ag Pd catalyst thin films. Cyclic voltammetry perchloric, nitric, sulfuric, phosphoric, hydrochloric, hydrobromic acid, pH 1, reveals that ORR...

Metformin in its protonated form as metformin hydrochloride is used worldwide an advanced antidiabetic drug for type 2 diabetes. Hyperinsulinemia and insulin resistance of cells are the main causes this disease. For patients with diabetes, (MET) works by improving cell sensitivity to insulin.
 It has been shown that methyl orange (MO) forms ionic associate can be isolated solid suitable cr...

Coated wire lithium ion selective electrode was fabricated using lithium ionophore-VI, 2-nitrophenyl octyl ether (NPOE) and potassium tetrakis(p-chlorophenyl)borate (KTpClPB) on platinum wire. Lithium ion selective electrode was giving Nernstian response from 10 -1 M to 10 -4 M with a detection limit of 3x10 -5 M. The calibration slope of this lithium ion selective electrode was found to be 58....

Conventional ion-selective electrodes with a liquid junction have the disadvantage of potential drift. All-solid-state ion-selective electrodes with solid contact in between the metal electrode and the ion-selective membrane offer high capacitance or conductance to enhance potential stability. Solution-casted chitosan/Prussian blue nanocomposite (ChPBN) was employed as the solid contact layer f...

in this research, a pvc membrane electrode for manganese (ii) ions based on n-(2-picolinamidoethyl)picolinamide as neutral carrier was prepared. the electrode exhibits a nemstian responseover mn(ii) concentration range of (1.0 x10-5 t01.0 x 10-1m) with a slope of 29.3±0.5 mv perdecade of concentration with a working ph range of 4.0-9.0. it has a fast response time (

In order to study the Cu(II) ion selective electrode, an optimized membrane was prepared by mixing of 30 mg of PVC powdered, 5 mg of considered ionophore, 60 mg of plasticizer and 5 mg of additive. The sensor showed a near Nernstian response for Cu(II) ions over a concentration range from 1.0×0-6 –1.0×0-2 M with a slope of 28.90.5 mV per concentration decade with a working pH range of 3.5-6.3. ...
