Extraction and characterization of humic acid from ...

Apr 20 2017 This study deals with the extraction and characterization of humic acids from low rank coals of Thar Chakwal and Quetta. Three respective coal samples were initially oxidized with 2 HNO 3 and then treated with 2.5 3 and 3.5 KOH solutions for the extraction of humic acid. The 3.5 concentration of KOH was found to be the optimum for the extraction of humic acid.
