【Abstract】 A wide variety of chemical and spectroscopic techniques has been used to determine functionality in humic subctances.Although NMR spectroscopy has been used for a much short period of time than most other techniques,this techniques has provided far more definitive information than all other methods combined.In this paper,we studied ~1H-NMR Spectroscopy of some humic and fulvic acids fractions from different soils in china.The proton spectum can assignment as:05-2.0ppm(aliphatic protons),3.0-6.3ppm(Proton on carbon at- oms adjacent to functional groups such as carbonyl groups;DOH Peak;asingle methoxyl),and 6:3-11ppm-(aromatic protons).We also caculated the proton’s relative content of the humic and fulvic acids and the result is shown in Tab.1更多还原
