Characterization of flue gas residues from municipal solid waste combustors
Article Abstract:
The treatment of flue gas from the combustion of municipal solid waste (MSW) is found to result in solid residues heterogeneously composed of glasses, metals and other crystals, detected of polluting elements. The study of the residues is important because of growing production rates and concentrations of potentially hazardous transition elements and heavy metals. The study showed that pollutant concentrations are not only affected by the composition of MSW, but also by the size of particles and flue gas treatment process.

Effect of landfill leachate organic acids on trace metal adsorption by kaolinite
Article Abstract:
Research into the effects of the organic acids hexanoic acid and fulvic acids in the absorption of trace metals from leachate by kaolinite showed that only fulvic acid is able to effect an enhancement of trace metal absorption and only at pH 5 and lower. The enhancing effect of the organic acids in trace metal absorption is closely tied to the ternary complexing ability of the substrate, which is a better indicator of the trace metal immobilizing ability of a landfill.

Acid/base, copper binding, and Cu2+/H+ exchange properties of goethite, an experimental and modeling study
Article Abstract:
Research into the effects of pH and the presence of hydrogen ion and copper ion on the mineral complexation properties of goethite showed that goethite's copper binding properties followed the triple-layer model and modified triple-layer model. This was seen in three pH, two ionic strength, three orders of magnitude in copper surface coverage and six order of magnitude in solution copper activity parameters.
