Sorption of colloids, organics, and metals onto gas-water, interfaces: Transport processes and potential remediation technology. 1997 annual progress report
'This research project has two objectives. The first is to improve basic understanding of contaminant interactions with gas-water interfaces, with emphasis on behavior of mixed contaminant systems. The second objective is to develop a sorptive microbubble fractionation remediation technique. Hypotheses supporting these objectives are: (1) contaminants and natural organics can sorb on and alter the interface hydrophobicity of the gas-water interfaces, and therefore influence sorption of colloids, metals, and radionuclides at gas-water interfaces; (2) surfactants can vastly increase sorption of colloids, metals and radionuclides selectively onto gas- water interfaces; (3) a sorptive microbubble fractionation remediation technique can be developed based on understanding of the previously mentioned processes. These hypotheses are being tested through quantification and visualization at both micro- and macro-scales.'
