Characterization of freeze dried and oven dried nitrohumic acids derived from the Mukah coal, Sarawak

Alkaline extraction was used to extract humic acids from Mukah coal. The alkaline solution used to perform this extraction is potassium hydroxide, KOH. Humic acids were extracted via oven-drying and freeze-drying approach. The characterization of oven-dried humic acids and freeze-dried humic acids w...
