In order to study the change of pore structure and adsorption characteristics coking coal after high-temperature high-pressure test, from Liulin coalmine was selected for research. Both mercury injection experiments were carried out on raw isothermal experiment processing with a pressure 11 MPa temperature ranging 30 90°C. The results show that is beneficial gas adsorption, while has restrainin...

Nonylphenol (NP) and bisphenol A (BPA) are two typical endocrine disrupter chemicals (EDCs) in reclaimed water. In this study, the adsorptions of NP, a branched NP (NP7) BPA on water-irrigated soils were studied by isothermal experiments, different environmental factors their investigated. The results showed that NP7 conformed to Linear model, adsorption Freundlich model. decreased with increas...

We report on the direct consequences of reversible water adsorption on the optical performance of silica-based nanoporous antireflective (AR) coatings as they are applied on glass in photovoltaic and solar thermal energy conversion systems. In situ UV-VIS transmission spectroscopy and path length measurements through high-resolution interferometric microscopy were conducted on model films durin...

PVA/PA6 composite nanofibers were formed by electrospinning. Cu(II)-PVA/PA6 metal chelated nanofibers, prepared by the reaction between PVA/PA6 composite nanofibers and Cu2+ solution, were used as the support for catalase immobilization. The result of the experiments showed that PVA/PA6 composite nanofibers had an excellent chelation capacity for Cu2+ ions, and the structures of nanofibers wer...

A precise experimental method for studying binary vapor-liquid equilibrium is to measure total pressure (P) as a function of the mole fraction in the liquid phase (2). The mole fraction in the vapor (y) is calculated from imthermal P-x experimental data using the Gibbs-Duhem equation. A similar procedure for adsorption is to measure total mass (m) of gas adsorbed as a function of the mole fract...

In this paper, two types of adsorption materials SA-C-Fe and SA-C-Fe(C) were prepared using bagasse biochar produced by one-step microwave pyrolysis activation for Cr(VI) removal wastewater. The characterized, performance, kinetics thermodynamics on studied. Results show that pyrolysis/activation contributes to developed pore structure abundant active functional groups, resulting in high capaci...
