a pvc-based membrane containing cerium phosphate was developed. unlike the cerium phosphate itself that acts as a cation exchanger, the membrane exhibited anion-exchange properties. therefore, the utility of this compound as a sensory element for detection of molybdate ions was pursued. the response of molybdate selective electrode based on this membrane was perfectly linear in the concentratio...

A liquid membrane disk electrode, LMDE, and a liquid membrane ring-liquid membrane disk electrode, LMRE-LMDE, were developed by placing a gelled polyvinyl chloride thin membrane impregnated with 2-nitrophenyl octyl ether, NPOE-LM, on the surface of a glassy carbon, GC, disk or ring electrode. The voltammogram for the ion transfer at the interface between an aqueous solution, W, and NPOE-LM was ...

A new nitrate-selective liquid-membrane electrode based on the tris(2,2',2"-salicylideneimino)triethylamine-iron(III) complex has been developed. This electrode exhibits a linear Nernstian response over the range 10(-1)-10(-4) M of nitrate, with a slope of 54.3 +/- 0.9 mV per p[NO3]. The effects of the pH and the liquid-membrane composition were also investigated. The lifetime of the electrode ...

A novel method for preparing enzyme membranes was developed. The enzyme was attached onto the electrode surface by dropping the enzyme solution and allowing it to dry. Glucose oxidase was used for entrapment. Then, the electrode surface was coated with an ionic liquid containing cellulose, and the ionic liquid was removed by immersing the electrode into water. Enzyme activity was retained in th...

N-(2H-[1,2,4]thiadiazolo[2,3-a]pyridine-2-ylidene)benzamide was used as a selective sensing material in the PVC membrane to construction of a new chromium ion selective electrode. This liquid membrane electrode worked well with a Nernstian response of 19.7 ±0.4 mV decade-1 of Cr(III) in a wide dynamic concentration range of 8.0× 10-6-1.0×10-1 M. The electrode had relatively short response time ...

a carbon nanocomposite electrode has been designed by incorporation of montmorillonite nanoclayinto the carbon ionic liquid electrode for the electrochemical determination of amitriptiline . the surface ofthe proposed electrode was characterized by scanning electron microscopy. the presence of ionic liquid asa binder is believed to be responsible for the electrocatalytic activity of the propose...
