What other effective methods are there for activating humic acid besides ammonification?

Reply #22010-11-19

For the activation of humic acid, relatively mature activation techniques are currently available; apart from ammonification, nitrification is another such method.

The nitration cost is a bit high. I’ve seen in some materials that alkali can be used for extraction, but I don’t know how to do it

Ammoniation and alkali extraction are one principle.

We are currently working on a project related to humic acid. The source of humic acid is lignite or peat. The extraction method is alkaline extraction; sodium hydroxide or ammonia can be used, or nitration with nitric acid can be employed.

Could someone upstairs tell me the ratio of sodium hydroxide to ammonia water? Or could it be sent directly to my email: chenminyuam@163.com. Thank you.
