In estuaries and marine environments, primary particles are frequently transported as large flocculated particles. This study provides, for the first time, evidence of in situ flocculation in Lake Geneva, a glacier-fed freshwater lake on the Swiss/French b ...
Lead and arsenic are among the designated chemicals of major concern by the World Health Organization, they affect millions of people worldwide with both acute and chronic effects on human health. In the current study, mixed matrix membranes (MMMs) were fa ...
The removal of sulfur compounds in biomass gasification processes is crucial to protect downstream equipment. While conventional sorbent materials can retain H2S, many fail to capture heterocyclic sulfur compounds such as thiophene (C4H4S). This work explo ...

Potassium hydroxide (KOH) modified network-type carbon spheres (CSs) with abundant oxygen-rich groups were synthesized using a simple hydrothermal carbonization (HTC) of glucose precursor and utilized for the adsorptive removal of cadmium(II) heavy metal a ...
Surface porosity affects the ability of a substance to adsorb gases. The surface fractal dimension D is a measure that indicates the amount that a surface fills a space, and can thereby be used to characterize the surface porosity. Here we propose a new me ...
The design of adsorption-based separation processes using novel adsorbents requires reliable data for the adsorption of fluid mixtures on candidate adsorbents. Due to the difficulty of generating sufficient data across possible operating conditions, proces ...
The effect of the micropore structure of activated carbon fibers (ACFs) on the adsorption of toluene at low concentration (10-80 ppmv) was studied over two types of ACFs. Both adsorbents presented similar surface chemistry but different porous structure: o ...
Aggregation of particles is fundamental for improving the performance of many solid/liquid processes. Aggregation can be induced by different means, and one of the most common is based on the addition of polymeric additives, namely polyelectrolytes. In thi ...
Contamination of the environment by anthropogenic volatile organic compounds (VOC) became of major concern during the last decades. Present in gas streams of many industrial exhausts, they are harmful and detrimental for both human health and environment e ...

The effect of surface functionalities, specific surface area and pore size of activated carbon fibers (ACFs) on the adsorption of toluene and acetaldehyde, two volatile organic compounds (VOC), at low concentrations (similar to 80 ppmv) and short contact t ...
