The treatment of air contaminated with toluene, ethylbenzene, and p-xylene was assayed in three laboratory-scale biofilters, each consisting of two modules connected in series, packed with a pelletized organic fertilizer and inoculated with a toluene-degrading liquid enrichment culture. Biofilters were

Polyethylene terephthalate (PET) is a polymeric material with high global demand. Conventionally, PET is produced from fossil-fuel-based materials. Herein, we explored the feasibility of a sustainable method for PET production by using solely bio-renewable resources. Specifically, 2,5-dimethylfuran (derived from lignocellulosic

GC Analysis of Xylene Isomers on SLB®-IL60

GC Analysis of Xylene Isomers on SLB®-IL60 - The cresol (methylphenol) isomers are also precursors to many chemicals. This chromatogram of a mix of aromatic and methylphenol compounds was generated using an SLB-IL60 ionic liquid column. Its interaction mechanisms allow the separation of all three xylene isomers, and all three cresol isomers.
