With the motivation to investigate role of coal physical structure on adsorption performance reservoir, 18 different types samples with structures were collected from six profiles four production mines located at China. The characteristics CH 4 examined, and then experimental results fitted analyzed by Langmuir model potential (D-R D-A). prominent factors in terms capacity its adaptability disc...

Activated carbons are universal adsorbents that can be obtained from a wide variety of raw materials, and have been found to be very effective for mercury removal from water. This contribution presents a comparative adsorption in column study of activated carbons obtained by physical activation of carbonized eucalyptus wood with water vapour, as adsorbents of mercury in liquid phase. Two sampl...

Control of surface properties in microfluidic systems is an indispensable prerequisite for successful bioanalytical applications. Poly(dimethylsiloxane) (PDMS) microfluidic devices are hampered from unwanted adsorption of biomolecules and lack of methods to control electroosmotic flow (EOF). In this paper, we propose different strategies to coat PDMS surfaces with poly(oxyethylene) (POE) molecu...

As kerogen is the main organic component in shale, the adsorption capacity, diffusion and permeability of the gas in kerogen plays an important role in shale gas production. Based on the molecular model of type II kerogen, an organic nanoporous structure was established. The Grand Canonical Monte Carlo (GCMC) and Molecular Dynamics (MD) methods were used to study the adsorption and diffusion ca...

The needs for safe, therapeutically effective antidiarrheal combination continuously lead to effective treatment. When administered simultaneously, metronidazole-kaolin interactions have been reported by FDA but not studied. This paper is the first to study metronidazole-kaolin interactions. Adsorption isotherms of a metronidazole-kaolin antidiarrheal combination from aqueous solutions at an in...

Removal of dissolved organic carbon (DOC) from water resulting from adsorption and microbial uptake was examined to determine the importance of biotic and abiotic pathways. Physical-chemical adsorption to components of the stream sediment or water and biotic assimilation associated with the microbial population was determined in recirculating chambers utilizing leachate from alder (Alnus rubru)...

Enhanced specificity in drug delivery aims to improve upon systemic elution methods by locally concentrating therapeutic agents and reducing negative side effects. Due to their robust physical properties, biocompatibility and drug loading capabilities, nanodiamonds serve as drug delivery platforms that can be applied towards the elution of a broad range of therapeutically-active compounds. In t...

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...

We present a theoretical model for the description of the adsorption kinetics of globular proteins onto charged core-shell microgel particles based on Dynamic Density Functional Theory (DDFT). This model builds on a previous description of protein adsorption thermodynamics [Yigit et al., Langmuir, 2012, 28], shown to well interpret the available calorimetric experimental data of binding isother...
