Abstract
The matrix solution behaviors of humic substances were studied by characterizing molecular weight distribution, hydrophilicity and others before and after batch tests of activated carbon treatment. Aquatic humic substances in peat water and pretreated peat water by alum coagulation were classified by size exclusion HPLC and Sep-Pak C-18 cartridge adsorption and extraction. The lower molecular weight and the less hydrophilic group has higher carbon adsorbability. Ideal adsorbed solution theory (IAST) using the Freundlich isotherm equation was used for the evaluation of adsorption isotherms of each classified groups of humic substances in batch adsorption experiments.
