Tetraazacyclohexadeca Macrocyclic Ligand as a Neutral Carrier in a Cr Ion-selective Electrode
A polystyrene-based membrane of 2,10-dimethyl-4,12-diphenyl-1,5,9,13tetraazacyclohexadeca-1,4,9,12-tetraene macrocyclic ionophore was prepared and investigated as Cr(III)-selective electrode. The best performance was observed with the membrane having the polystyrene-ligand-dibutylphthalate-sodiumtetraphenyl borate composition 1:4:1:1 with a Nernstian slope of 19.0 mV per decade of concentration...
متن کاملChromium(III) ion selective electrode based on 2H-1,4-benzothioazine-2,3(4H)dione dioxime as a neutral carrier
A poly(vinyl chloride) membrane based on a new a-dioxime derivative as membrane carrier was prepared andinvestigated as a Cr(III) selective electrode. The electrode exhibits a good potentiometric response for Cr(III)over a wide concentration range 1.0 x 10-6 to 1.0 x 10-1 M with a slope 19.5+0.5 mV/decade and low detectionlimit of 8.9 x 10-7 M. It has a fast response time < 15 s. The best perfo...
متن کاملDetermination of Mn2+ in Pharmaceutical Supplements by a Novel Coated Graphite Electrode Based on Zolpidem as a Neutral Ion Carrier
Manganese plays a key role in the health of human beings therefore, its determination is very important in medical fields. In this regards, a novel coated graphite electrode was constructed for determination of manganese (II) by using zolpidem as an ionophore, for the first time. The best performance was obtained of the membrane composition of PVC (32%), Potassium tetrakis (4-chlorophenyl) bora...
متن کاملA mercury(II) ion-selective electrode based on N,N-dimethylformamide-salicylacylhydrazone as a neutral carrier.
A new PVC membrane mercury(II) ion electrode based on N,N-dimethylformamide-salicylacylhydrazone (DMFAS) as an ionophore is described, which shows excellent potentiometric response characteristics and displays a linear log[Hg(2+)] versus EMF response over a wide concentration range between 6.2 x 10(-7) and 8.0 x 10(-2) M with a Nerstian slope of 29.6 mV per decade and a detection limit of 5.0 x...
متن کامل(1E,2E) -bis (2-aminophenyl) N'1,N'2-dihydroxyethane bis (imidothioate) as a neutral carrier in ion-selective electrode for Ni(II) and it computational studies
A PVC membrane Ni(II) ion selective electrode has been constructed using (1E,2E)-bis(2-aminophenyl)N'1,N'2-dihydroxyethanebis as membrane carrier. The electrode exhibited a goodpotentiometric response for Ni(II) over a wide concentration range 1.0×10-4 to 1.0×10-1M with aslope of 29.4±0.5 mV/decade a and a working pH range of 6.5-9.0. It had a fast response time of≤20s. The best performance was...
