A cheaper method to recycle activated carbon

https://phys.org/news/2022-12-cheaper-method-recycle-carbon.html

"Fe-PAC-based adsorption-regeneration... relatively low cost of ≈$0.35 kg-1 shows higher regeneration efficiency (70.5–92.7%), lower loss rate of absorbent (≈8.25% per cycle), as well as lower H2O2 dosage (2.31 g g(PAC)-1)... atomic dispersion sites in PAC regeneration. This promising strategy for PAC regeneration shows bright and broad application prospects in large-scale cost-effective wastewater treatment including contaminants like methylene blue and crystal violet"
