It is reducible to a fine powder by trituration, and if submitted to the action of a weak solution of potash, it yields a considerable quantity of humic is an oxidized form of lignite, which also contains high levels of humic acid.
The humic acid obtained after this process was subjected to evaluate the minerals and characterized by using FESEMEDAX method. The growth parameters of Vigna mungo was studied after applying optimized humic acid. Keywords: Lignite, Humic acid, RSM, CCD, Vigna mungo, FESEM – EDAX. INTRODUCTION AND EXPERIMENTAL
Three respective coal samples were initially oxidized with 2% HNO3 and then treated with, 3, and % KOH solutions for the extraction of humic acid. The % concentration of KOH was found to be the optimum for the extraction of humic acid.
