Coated-wire Lithium lon-selective Electrodes Based on Polyal koxylate Complexes

Gadzekpo, Victor P. Y.; Moody, G. J.; Thomas, J. D. R. (University of Cape Coast, 1985-01-01)

Barium and lithium adducts of polyalkoxylates have been investigated as sensors in lithium ion-selective electrodes using a microconduit flow injection analysis system. Dioctyl phenylphosphonate (DOPP) and dioctyl ...
Intramolecular photochemical electron transfer

Schmidt, John A.; Jing-Yao, Liu; Bolton, James R.; Archer, Mary D.; Gadzekpo, Victor P. Y. (University of Cape Coast, 1989)

The compound PAQ, which consists of a tetra-arylporphine attached to methyl-p-benzoquinone via a single amide linkage, exhibits light-induced intramolecular electron transfer from the porphyrin excited-singlet state to the ...
Solvent dependence of photochemical electron-transfer rates in a covalently linked porphyrin-quinone molecule

Arches, Mary D.; Gadzekpo, Victor P. Y.; Bolton, James R.; Schmidt, John A.; Weedon, Alan C. (University of Cape Coast, 1986)

The solvent dependence of intramolecular photochemical electron-transfer rate constants in a covalently linked porphyrin-amide-quinone molecule (PAQ) has been found in nine solvents to correlate reasonably well with the ...
Studies of Spectrophotometric Reagents in Some Transition Metal and Lead Ion-selective Electrodes

Quagraine, Emmanuel K.; Gadzekpo, Victor P. Y. (University of Cape Coast, 1992)

The general performance of ten spectrophotometric reagents, namely salicylaldoxime, 22'-dipyridyl, dimedone, 8-hydroxyquinoline, dithiooxamide, cupferron, nioxime, 4-methylnioxime, 1,lO phenanthroline hydrate and a-benzoin ...
Use of a flow-injection system in the evaluation of the characteristic behavior of neutral carriers in lithium ion-selective electrodes

Xie, Robert Y.; Gadzekpo, Victor P. Y.; Kadry, Azza M.; Yehia, Ibrahim A.; Ruzicka, Jaromir; Gary, D. Christian (University of Cape Coast, 1985)

A flow-injection system based on microconduits is used to investigate electrode characteristics such as selectivity, detection limit, and response and equilibrium times of the new ionophore, N,N,N’,N’-tetraisobutyl-5,5-d ...
Voltammetric detection of the polycation protamine by the use of electrodes modified with self-assembled monolayers of thioctic acid

Gadzekpo, Victor P. Y.; Xiao, Kang Ping; Aoki, Hiroshi; Buhlmann, Philippe; Umezawa, Yoshio (University of Cape Coast, 1999)

The detection of protamine, a polycation, by use of electrodes modified with self-assembled monolayers of thioctic acid is reported. These sensors can detect protamine concentrations as low as 0.5µg/mL when [Ru(NH3)6]3+ ...
