The process of nitration reaction of peat humic acid has been investigated by analyzing the different effect for different reaction condition(such as
reaction time and the concentration of nitric acid).The effects include the contents of nitrogen and nitrate nitrogen
the contents of nitrate nitrogen after alkali hydrolyzation.The yield of the nitration of humic acid will reduce with the increase of nitrate concentration and the extension of the reaction time.The value of E4/E6 will increase;it proved that t...
