Abstract
The harmful in fluence of humic acids in solution on uranium solvent extraction is investigated. The influence is poor phase separation and forming stable emulsion when uranium is extracted or stripped and decreasing uranium loading of organic phase. Extractions of organic matter and solvent extraction of uranium were carried out from three sedimentary uranium deposits. The results show that stable emulsions of W/O or O/W type were formed separately with organic solvent containing tertiary amine or D{sub 2}EHPA to extract uranium from uranium liquors containing humic acid. Several humic acids of different molecular weight were fractionated by means of fractional solution containing various volume ratios of ethanol and ethyl acetate. The physical properties and chemical composition of the humic acid were determined. It was found that there was distinct difference in emulsion-causing between the humic acids having different molecular weight. The removal methods of humic acid from aqueous and organic solution were discussed briefly.
