Interactions of cupric ion with humic acid. Master's thesis

Technical Report ·
OSTI ID:7301660

The properties of coal humic acids were examined with the objective of determining their suitability for removing some of the major pollutants associated with the mining and use of coal. The preparation and characterization of coal humic acids is described. Their acid-base and precipitation behavior were determined. Rates and equilibria for leaching of copper from insoluble copper salts by coal humic acids were measured. The formation constants of soluble copper humate chelates were measured. Binding of copper by insoluble coal humic acids in acidic media was investigated. Even at pH values as low as 2, copper is bound to insoluble coal humic acid in water.
