- W810271994 abstract "Industrial activities and accidental releases often introduce a large amount ofinorganic and organic contaminants to the environment. Humic substancesinteract strongly with metals and organic pollutants. In this study, this propertywas exploited in order to establish new remediation materials in twoenvironmental applications and in one pharmaceutical application. The tworemediation materials under investigation were sludge and sediment, ST sludgeand CE sludge, respectively.The first application aimed at investigating the use of the remediation materialsto remove arsenic, iron, and uranium from the industrial effluents. The mainresults were the release of iron from ST sludge inhibited its usage asremediation material whereas CE sludge showed excellent performance. Theextractions were both rapid and efficient. The second application studied theextraction of organic contaminants. The objective of this study was to find anew remediation material for removal of organic contaminants. The remediationmaterials showed similar and excellent performance on extraction ofchlorinated anilines, phenols and benzenes. The third application investigatedthe extraction of iodine species from urine. It aimed at determining whether theradioactive iodine can be extracted from the urine and thereby concentratedinto a smaller volume of solid. Even though the extraction percentages fromurine were not as promising as from deionised water and synthetic urine,scientific interest was raised and further investigations on the effect of thecomposition of urine and solubility of sludges for the extraction of iodinespecies were recommended.The outcome of the presented study was interesting both scientifically andeconomically. The promising extraction results for arsenic, iron and uraniumindicate that the CE sludge is ready to be tested in a field study. The extractionof organic compounds by both remediation materials was also promising.However, further studies on permeability and solubility were recommended." @default.
