The effects of nitrify reaction on reactive functional groups of peat humic acid have been systematically analyzed

the change orderliness being discussed of reactive functional groups of peat humic acid with nitrification reaction. The results show that the reactive functional group and carboxyl of the peat humic acid in the nitrification reaction has a big range increase

but the phenolic hydroxyl group only has a little increase. Earlier the con- tent of the quinone group was increased with the degree of o...
