Influence of Pb(II) on the radical properties of humic substances and model compounds.
The influence of Pb(II) ions on the properties of the free radicals formed in humic acids and fulvic acids was investigated by electron paramagnetic resonance spectroscopy. It is shown that, in bothExpand

Thermodynamics of adsorption of dithiocarbamates at the hanging mercury drop.
Two dimethyldithiocarbamate (DMDTC) pesticides, thiram and ziram, are adsorbed onto a Hg drop via an entropically driven process. The adsorption isotherms are described by the Frumkin equation. ForExpand

Interfacial thermodynamics of gallic acid adsorption on a chargeable hydrophobic surface.
The thermodynamics of adsorption of gallic acid (GA, 3,4,5-trihydroxylbenzoic acid) on the hanging mercury drop electrode (HMDE) surface was studied by temperature-dependent stripping voltammetryExpand

Adsorption and radical stabilization of humic-Acid analogues and Pb2+ on restricted phyllomorphous clay.
Humic acids have stable radicals that are indigenous to their structure. Hydroxybenzoic acid derivatives such as gallic acid (GA) and protocatechuic acid are appropriate models for the radicalExpand
