Relationship between the Chemical Structure of Humic Substances and Their Hygroscopic Properties

  title={Relationship between the Chemical Structure of Humic Substances and Their Hygroscopic Properties},
  author={Osamu Sasaki and Isamu Kanai and Yuuki Yazawa and Tatsuaki Yamaguchi},
We investigated the relationship between the hygroscopic properties and chemical structures of humic and fulvic acids. Humic and fulvic acids were extracted from andosol, Canadian peat and Chinese weathered coal using the IHSS method. Fulvic-like organics produced by the ozone oxidation of humic acid were also prepared by a method reported previously. Their main chemical properties related to hygroscopicity were also studied by elemental analysis and the measurement of functional group contents… CONTINUE READING
