In this study a simple, highly sensitive, and selective electrochemical method was developed for determination of the low concentration curcumin (CUR) using a poly(vanillin-co-caffeic acid) p(Van-CA) modified platinum electrode. Electrode modification was carried out electrochemically with cyclic voltammetry (CV) method. For this purpose; a solution of 6 mM vanillin (Van) and 6 mM caff...

In this paper, a novel membrane triiodide sensor based on a charge-transfer complex of (1,3-diphenyldihydro-1H-imidazole-4,5-dionedioxime) with iodine (CTCI) as a membrane carrier is introduced. The best performance was obtained with a membrane containing 30% polyvinylchloride (PVC), 63% dibutylphthalate (DBP), 5% CTCI and 2% hexadecyltrimethylammonium bromide (HTAB). The electrode shows a Nern...

Solid electrolytes used in all-solid-state batteries electronically separate the positive and negative electrodes battery only allow carrier ions to pass through. KTiOPO 4 (KTP), a potassium ion-conducting solid electrolyte, was first applied as inner contact layer of an ion-selective electrode (ISE) stabilize membrane potential. Application KTP improved long-term potential stability ISE by sta...

A novel membrane coated platinum-wire electrode (MCPWE) based on N,N'-bis(2-thienylmethylene)-1,2-diaminobenzene (BTMD) for highly selective determination of Ag+ ion has been developed. The influences of membrane composition and pH on the potentiometric responses of electrode were investigated. The potentiometric responses are independent of the pH of the test solution in the range of 5.0 - 9.0...

A description for the ligand function of tetrathiocyanatozincate selective electrode, has been proposed, using a multi-species approach model. This model takes into account simultaneous phase-boundary, diffusion-controlled, processes ion exchange between tetrathiocyanatozincate, thyocyanate and foreign ions unable to form zinc complexes, as well distribution neutral complex phases, partial deco...
