This carbon is formed by using the regular activated carbon through modification and thermal treatment to create the unique activated carbon as an oxidation catalyst especially for Glyphosate. It takes less reaction time and less energy consumption compared to the traditional technology. Besides, the active groups have a high probability of being embedded on the surface of activated carbon, which saves the cost a lot for the manufacturers and also improves the competitiveness in the market. Meanwhile, this activated carbon would improve the conversion rate of PMIDA, which would lead to the increase of Glyphosate production. It is mainly used in the decolorization and refining of refined sugar, xylose, fructose, glucose, fruit juice and alcohol, food chemistry and brewing industry.
