چکیده مقاله:

A PVC membrane Fe(III) ion selective electrode has been constructed using a new macrocyclic asmembrane carrier.The electrode exhibits a good potentiometric response for Fe(III) over a wideconcentration range 1.0×10-4 to 1.0×10-1M with a slope 19.4±0.5 mV/decade a and a working pHrange of 6.5-9.0. It has a fast response time ≤30s.The best performance was observed with themembrance having the 30.5% PVC,3.0% ligand, 61.0% acetophenone and 5.5% oleic acidcomposition.

A Novel Carbon Paste Electrode for Potentiometric Determination of Vanadyl Ion

Carbon paste electrode was modified by disodium 2,4-diamino-7-methylbenzo[g] pteridine-5,10-dioxide to fabricate a sensor for potentiometric determination of vanadyl ion (VO2+) in aqueous medium. The new ligand was synthesized in three steps with high yield. The optimal composition of the carbon paste was made of graphite powder (64.5%), ionophore (16.6%), paraffin oil (17.8%), a...

Determination of Cobalt(II) by a New PVC Membrane Coated Graphite Electrode Based on 6-chloro-11- azabenzo[a]phenothiazin-5-one as a neutral ion carrier

Cobalt has great biological effects on human beings and also other living organisms, hence its determination is very important. In this regard, a novel coated graphite electrode was designed for determination of Co2+ ions by exploiting 6-chloro-11- azabenzo[a]phenothiazin-5-one as a neutral ion carrier, for the first time. The foremost function was witnessed from the membrane composition of PVC...
