Characterization of proton and copper binding properties of natural organic matter from an Australian drinking water source by differential absorbance spectroscopy
MetadataShow full item record
This study examined the effects of changes in pH and copper concentration on the absorbancespectra of natural organic matter (NOM) from a reservoir in Western Australia. Differentialabsorbance spectra generated for this NOM under changing pH and copper concentrationconditions revealed features that could be correlated to the activity of distinct types ofchromophores. A comparison of results with those generated for experiments with standardSuwannee River fulvic acid highlighted important differences in chemistry between the twosamples.
