Conversion of fruit waste-derived biomass to highly microporous activated carbon for enhanced CO capture.

Activated carbons were prepared from different Amazonian fruit waste-derived biomass residues from the Amazon to store CO at low pressure. The samples were carbonized in under flowing N flow atmosphere and activated with KOH. The carbon materials obtained were physically and structurally characterized by the analysis of N isotherms for textural characterization, X-ray fluorescence (XRF), ash content, X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM), and applied for CO adsorption.

Comparative study of the adsorption of acetaminophen on activated carbons in simulated gastric fluid.

Samples of commercial activated carbons (AC) obtained from different sources: Norit E Supra USP, Norit B Test EUR, and ML (Baracoa, Cuba) were investigated. The adsorption of acetaminophen, Co = 2500 mg/L, occured in simulated gastric fluid (SGF) at pH 1.2 in contact with activated carbon for 4 h at 310 K in water bath with stirring.
