AI Technical Summary

Technical Problem

Conventional methods for extracting humic substances from coal via chemical oxidation are costly due to high expenses associated with oxidizing agents and processes, achieving a yield of only 75% humic acids, whereas the new method employs sonication milling and ultraviolet irradiation with hydrogen peroxide to enhance surface contact and radical oxidation, achieving a 95% yield.

Method used

The method involves milling coal using sonication to reduce particle size to 10-100 microns, followed by oxidation with hydrogen peroxide under ultraviolet light, specifically in the 200 nm wavelength range, to maximize hydroxyl radical production and enhance coal oxidation, thereby increasing humic acid extraction efficiency.

Benefits of technology

This approach significantly increases the yield of humic acids to 95% compared to conventional methods, demonstrating improved extraction efficiency and cost-effectiveness by maximizing surface contact and radical oxidation.
