AB  - Humic substances (HS) are very heterogeneous, and preferential adsorption of 
      certain components takes place during their interaction with minerals. Our 
      results indicated that for fulvic acid (FA) the relatively large (3.6-18.2 kDa) 
      particles were preferred in the adsorption to goethite, whereas for humic acid 
      (HA) the intermediate sized (3.6-12.0 kDa) fractions were preferred. Correlations 
      between molar mass (M(w)) and specific UV absorption values (SUVA) with ratios of 
      UV light absorbance (E(2)/E(3), E(4)/E(6)) were observed. The adsorption did not 
      change the relation between E(2)/E(3) and M(w), E(4)/E(6) and SUVA. The E(2)/E(3) 
      and E(4)/E(6) can probably be used as indicators of molar mass and aromaticity of 
      HS in studying the preferential adsorption. The adsorption of HA and FA to 
      goethite was fast and reached a steady state in about 6 h. The intermediate sized 
      HA particles (3.6-12.0 kDa) were adsorbed quickly, and part of them was 
      subsequently replaced by somewhat larger particles (>50 kDa). For FA, 
      preferential adsorption of relative large particles (3.6-18.2 kDa) took place 
      quickly, and there was a limited substitution by particles with higher 
      aromaticity. Without specifying the property especially the molar mass range of 
      HS under study, confusion can arise from researches using different HS materials.
