Raising Productivity of Fulvic Acid from Peat via Oxido-Degradation with Nitric Acid
【Abstract】 The oxdio-degradation of peat by nitric acid followed with extraction of humic acid(HA) and fulvic acid(FA) by sodium hydroxide has been carried out to increase the productivity of FA from peat. The additional FA could be obtained from filtrate by precitation with Al 2(SO 4) 3 solution. At optimum conditions the extracts of HA and FA from peat were 45.11% and 7.88%, respectively.
