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...

The current study focused on utilizing cobalt oxide to eliminate hazardous Eriochrome Black T (EBT) dye. impact of pH (2, 4, 7, 8, and 10) temperature (45, 50, 55 °C) was examined for EBT removal. results show that the maximum sorption occurred at = 2 removal percentage increased with increasing temperature. Five non-linear regression methods were used predict best isotherm kinetic models. A co...

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...

Physical and geochemical characteristics of shale play conclusive role in confirming operation measures during drilling and stimulation. The properties of shale samples from Jiyang depression were investigated through X-ray diffraction, scanning electron microscope, adsorption isothermal, high pressure mercury intrusion, methylene blue trihydrate, pressure pulse decay, tests of specific water w...

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...

TEMPO-Oxidized cellulose nanofibrils (toCNF), in the form of highly entangled network such as membrane or cryogels, have proven to be interest for various applications, including drug release purification by pollutant adsorption. β-Cyclodextrins (β-CDs) ability inclusion complexes with large amount hydrophobic molecules, and are considered a promising way bring new functionalities these materia...

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...

In recent years, the removal of dyes has emerged as a significant problem that attracted several researchers. The search for green and eco-friendly adsorbents been never-ending task in environmental protection to overcome this issue. Herein, almond shells (AS) were used an adsorbent remove methyl orange (MO) from aqueous solutions. AS was characterized using techniques such X-ray diffraction (X...
