Critical coagulation in sulfidic sediments from an east-coast Australian acid sulfate landscape

MacDonald, Bennett; Reynolds, Jason K; Kinsela, Andrew; Reilly, Richard; van Oploo, P; Waite, T; White, Ian

Description

Sulfidic clays are agriculturally and environmentally important. In this work we examine the impacts of electrolytes and pH on the behaviour of colloidal clay mineral particles extracted from such sediments. The distribution of ferrous iron released by pyrite oxidation, aluminium by acidic weathering and cations in soils and pore waters in the field are reported. The behaviour of open-structured sulfidic colloidal clay mineral particles in response to changes in solution ionic composition were...[Show more]
