Deposition of colloidal hematite onto mercury from water-ethanol mixtures

Mostrar todas las versiones(2)

The adherence of hematite (αFe2O3) particles onto mercury electrodes in water-ethanol mixtures has been studied by counting using optical microscope images. The number of attached particles, when the ethanol content is small, decreases as the ethanol concentration increases. At a mole fraction of et...
