Abstract Natural adsorbents are a good alternative to remove antibiotic residues from wastewater. In this study, the adsorption capacity of sulfamethoxazole (SMX) onto sugarcane bagasse (SB) and corn cob (CC) in continuous fixed-bed was compared. Brunauer Emmett Teller, Fourier transform infrared (FTIR), Boehm titration, point zero charge (pH pzc ) were used characterize both adsorbents. The (q...

Eminent nuclear experimentalist Felix Hans Boehm passed away on 25 May 2021, a few days before his 97th birthday. His scientific career spanned the second half of 20th century and coincided with evolution experimental physics—from “in-house,” relatively small-scale experiments performed by handful physicists to large-scale efforts at an external facility significant group participants. Those ma...

Abstract In this study, polyacrylonitrile (PAN)-based carbon fiber with high nitrogen content was activated at 800 °C sodium carbonate and heat-treated 950 to prepare (ACF), the results of nitrate ion adsorption on prepared ACF are presented. CHN elemental analysis, XPS measurement, Boehm titration were used determine surface functional groups ACF. It is discussed that total amount decreases, w...

Recounts the career and contributions of Barry Boehm.

In the context of circular economy, used coffee grounds were transformed into powdered activated carbon by chemical activation using potassium hydroxide. Its characterisation was conducted in comparison with that a commercial scanning electron microscopy (SEM) coupled energy dispersive X-ray microanalysis (EDX), diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Boehm titration,...

Activated carbons (ACs) obtained from coffee husk by KOH activation at 650 (ACK-650) and 750oC (ACK-750), were used as an adsorbent for the adsorption of phenol aqueous solution. The ACs was characterized SEM, EDX, BET, Boehm titration techniques. experimental equilibrium data analyzed eight isotherm models, which are four two-parameter equations (Langmuir, Freundlich, Elovich, Temkin) three-pa...
