Abstract:The structure characteristics and adhesive property of humic substance (HS) extracted with different methods were mainly studied by terms of elementary analysis, visible spectrum, FT-IR spectroscopy, viscosity, adsorption and pelletizing experiments. The results show that HSs extracted with new method (HS-a) own higher degree of aromatization and polymerization, larger relative molecular mass and more polar functional groups than HS extracted with usual method (HS-b). The viscosity of HS-b is about 30–40 mPa·s lower than that of HS-a. The maximum adsorption amounts of HS-a and HS-b onto iron c
