AI Technical Summary
Existing biochar materials have poor adsorption and removal effects on organic pollutants such as dyes and antibiotics, and the development of agricultural and forestry waste resources is insufficient, resulting in low added value.
The preparation method of biochar activated by potassium salt of polyphenolic hydroxy organic acid includes pre-carbonization, hot solution impregnation of polyphenolic hydroxy organic acid, potassium hydroxide solution impregnation and high-temperature pyrolysis, to form a biochar-based adsorbent with high specific surface area and well-developed pore structure.
This improved the adsorption performance of biochar, enabling rapid and efficient removal of organic pollutants such as dyes and antibiotics, and enhancing the added value of biomass resources.
