چکیده
The work described here comprises the determination of Fe(III) by ion selective potentiometry using a coated-wire ion-selective electrode (CWISE) based on iron–cyclam complex. Linear Nernstian response for this electrode was obtained over the total Fe(III) concentration range of 1× 10−2 to 1× 10−6 M in 0.05 M HNO3, H2SO4, HClO4, HCl, KNO3 and KCl media, with a slope of 60± 5 mV per decade change. Working pH range of the electrode was found to be 1.3–3.5. Selectivity coefficients of some monoand divalent metal ions were determined. A t ©

A coated-wire ion-selective electrode (ISE) based on cyclam (1,4,8,11-tetraazacyclotetradecane) as a neutral carrier in a polyvinyl chloride (PVC) matrix was fabricated for the determination of Ag(I) ions. The coated-wire ISE exhibited a linear Nernstian response over the range 1 x 10(-1) to 1 x 10(-7) M with a slope of 59 +/- 2 mV per decade change and a detection limit of 5 x 10(-8) M. The IS...
متن کاملA Mononuclear Nonheme Iron(III)-Peroxo Complex Binding Redox-Inactive Metal Ions.
Redox-inactive metal ions that function as Lewis acids play pivotal roles in modulating reactivities of oxygen-containing metal complexes in a variety of biological and biomimetic reactions, including dioxygen activation/formation and functionalization of organic substrates. Mononuclear nonheme iron(III)-peroxo species are invoked as active oxygen intermediates in the catalytic cycles of dioxyg...

We present a systematic study using density functional theory (DFT) and coupled cluster (CCSD(T)) computations with an aim of characterizing a non-heme ferric-superoxo complex [(TMC)Fe(O2)](2+) (TMC = 1,4,8,11-tetramethyl-1,4,8,11-tetraazacyclotetradecane) that was proposed to perform allylic C-H activation of cyclohexene (Lee, Y.-M. et al. J. Am. Chem. Soc.2010, 132, 10668). As such, we invest...
