"Deciphering the Micron-Scale Adsorption Revolution of Powdered Activated Carbon"

Core content:

Microstructure: Synergistic effect of particle size distribution (5-50μm) and mesoporosity (40-60%)

Adsorption kinetics:

Specific surface area>1500㎡/g, 2 times higher adsorption rate than granular carbon

The pollutant diffusion path is shortened to 1-5μm (1/10 of traditional granular carbon)

Modification breakthrough:

• Iron oxide loaded type: Arsenic adsorption capacity reaches 35mg/g

• Nitrogen doped type: Adsorption selectivity for phenol is increased by 80%
