Hypothesis
Can microbial pretreatment of brewer's grain enhance the adsorption performance of activated carbon for toluene?
Conclusion
Microbial pretreatment significantly improves the adsorption capacity of activated carbon for toluene.
Supporting Evidence
- The activated carbons prepared by microbial pretreatment had a rougher morphology and higher specific surface area.
- AC-AN and AC-AO showed better adsorption performance for toluene compared to untreated activated carbon.
- The adsorption capacity of AC-AN increased by 31.5% and AC-AO by 18.3% compared to untreated carbon.
Takeaway
Using special fungi to treat brewer's grain makes better carbon that can soak up more toluene, a harmful gas.
Methodology
Activated carbons were prepared from brewer's grain pretreated with Aspergillus niger and Aspergillus oryzae, and their adsorption performance for toluene was evaluated.
Limitations
The study may not account for all types of VOCs or other environmental conditions affecting adsorption.
