This study evaluates how the characteristics of activated carbon (AC) influence the adsorption–reduction of bromate (BrO3−) by performing inetic and isotherm tests. Experimental results reveal that both physical and chemical effects simultaneously affect the adsorption–reduction rocess. The wood-based carbons contained more mesopores than coconutand coal-based carbons, resulting in the adsorpti...

Background and purpose: Chromium hexavalent compounds are carcinogens that are found in groundwater as chromate and dichromate negative ions. The aim of this study was to remove Cr (VI) from water by activated carbon modified with cationic surfactant alkyl dimethyl benzyl ammonium chloride (Benzalkonium chloride). Materials and methods: In terms of the Critical Micelle Concentration (CMC) of...

Abstract To contribute to the reduction of methane emissions, using low-cost biochar as adsorbents for capturing and storing in oil gas fields is investigated. This work presents results adsorption on four biochars made from forestry wastes comparison with three commercial activated carbons. Although capacity lower by over 50% than that carbons, thelow-cost potential environmental benefits prov...

An efficient storage of hydrogen is a crucial requirement for its use as a fuel in the cars of the future. Experimental and theoretical work has revealed that porous carbons are promising materials for storing molecular hydrogen, adsorbed on the surfaces of the pores. The microstructure of porous carbons is not well known, and we have investigated a class of porous carbons, the carbide-derived ...
