Abstract:
Recent advances in adsorptive gas separations have focused on the development of porous materials with high operating capacity and selectivity, useful parameters that provide early guidance during the development of new materials. Although this material-focused work is necessary to advance the state of the art in adsorption science and engineering, a substantial problem remains: how to integrate these materials into a fixed bed to efficiently utilize the separation. Structured sorbent contactors can help manage kinetic and engineering factors associated with the separation, including pressure

Abstract:
Liquefied Natural Gas (LNG) must be vaporized before it is used in the combustion process. In most regasification terminals, energy that was previously expended to liquefy natural gas is dissipated in the environment. The paper proposes the use of the thermal effect of LNG regasification for the atmospheric air separation as a possible solution to the LNG exergy recovery problem. The presented idea is based on the coupling of the LNG regasification unit with an oxygen generator based on the Temperature Swing Adsorption (TSA) process. Theoretical analysis has revealed that it is thermodynamical

Within three decades of fundamental findings in research on metal–organic frameworks (MOFs), a new family of hybrid materials known as gallate-based MOFs, consisting of metal salt and gallic acid, have been of great interest. Due to the fact that gallic acid is acknowledged to display a range of bioactivities, gallate-based MOFs have been initially expended in biomedical applications. Recently, gallate-based MOFs have been gradually acting as new alternative materials in chemical industrial applications, in which they were first reported for the adsorptive separation of light hydrocarbon separ

Abstract:
Most chromatographic separations are based on chemical interaction between the solute of interest or impurities to be removed and the separation medium. The exception is separations based upon physical properties such as size (e.g. size exclusion chromatography) or transport in a force field (e.g. electrochromatography). The chemical interaction may be weak (e.g. employing van der Waals forces) or very strong (e.g. involving formation of chemical bonds as in covalent chromatography). Whenever separation is based upon attractive forces between the solute and the separation medium, we talk about adsorption chromatography (also when the solute is merely retarded). The chemical interaction between the solute and the adsorbent (the chromatography medium) is governed by the surface properties of the solute and the adsorbent and is in most cases mediated by the mobile phase or additives to the mobile phase. Macromolecules such as proteins display a variety of properties and, ideally, a selected set of properties is utilized for obtaining the required selectivity (i.e. relative separation from other solutes) using a separation medium of complementary properties. This chapter briefly reviews the different types of forces of interaction between solutes and surfaces commonly employed for chromatographic purifications, important properties of solvents, and some basic surface chemical properties of proteins. This, together with a description of some common types of chromatography modes provides a basis for a rational selection of separation mechanism for the purification of proteins and the choice of mobile phase composition to regulate the relative influence of different interaction mechanisms. The separation mechanisms are focused to adsorptive modes with the exception of affinity chromatography which is discussed in Chapter 9. The different attractive forces acting between molecular and particle surfaces include (1): • dispersion forces • electrostatic dipole interactions • electron donor-acceptor forces • formation of covalent bonds All these forces are due to interactions between electric charges (permanent or induced). Dispersion, or London forces, are caused by induced dipole-induced dipole interactions and are thus classified as a non-specific interaction. This type of non-polar interaction is the dominant force promoting dissolution of non-polar solutes in organic solvents.

Most countries worldwide face the problem related to clean and safe water. The major source of contamination of water bodies includes the discharges of wastes from various domestic and industrial sources (heavy metal ions, dyes, and pharmaceuticals). To overcome those problems, various water purification methods such as coagulation, flocculation, adsorption, membrane separation, biological, and electrochemical methods have been engaged. Adsorption using nano-biosorbents based on chitin, chitosan and modified chitosan, cellulose, alginate, micro algal has emerged as a better alternative for the removal of contaminants from drinking and wastewater treatment. The main advantages of these nano-biosorbents include its biodegradability and eco-friendliness, which have attracted researchers to this field.

Abstract:
Chitosan, known as a most typical marine biological polymer, has a fruitful capability of biocompatible gel formation. Attempts of chitosan have been made to develop it from the multifaceted viewpoint of separation technology. The physicochemical properties of chitosan containing a lot of hydroxyl groups and reactive amino groups help to build the characteristic polymer networks. The deacetylation degree of chitosan is found as the most influential factor to regulate properties of chitosan hydrogels. The antibacterial activity of the chitosan membrane is one of its notable abilities because of its practical application. The chitosan, its derivatives, and the complex formation with other substances has been used for applications in filtration and membrane separation processes. Adsorption processes based on chitosan have been also developed widely. Moreover, complex of chitosan gel helps to immobilize adsorbent particles. The chitosan membrane immobilizing Prussian-Blue for cesium ion removal from the aqueous phase is one of the leading cases. To elaborate the adsorption behavior on the chitosan immobilizing adsorbent, the isothermal equilibrium and mass transfer characteristics can be discussed. The adsorption process using chitosan-based membranes in combination with filtration in a flow process is advantageous compared with the batch process. More advanced studies of chitosan aerogel and chitosan nanofibers have been proceeded recently, especially for adapting to water purification and air filtration.

Abstract:
The development of cost-effective, efficient and stable materials helps to provide the affordable solutions to get safe and fresh water to increasing population with health guidelines of emerging contaminants. Nanomaterials (NMs)-based techniques involve the design, synthesis, manipulation, characterization and exploitation of materials for adsorption and separation of target species from the contaminated and waste water. NMs show better adsorption capacity and catalytic for number chemical species and microbes because of their small size and large surface area that favors the purification and treatment of waste or contaminated environmental water. Here, we present the chemical properties, adsorption/removal mechanism and applications of advanced NMs such as magnetic nanoparticles (MNPs), carbon nanotubes (CNTs), graphene and graphene oxide (GO), titanium oxide (TiO2), silica (SiO2), silver (Ag), gold (Au) NPs and zeolites in effective and efficient removal of toxic metal ions, organic and inorganic chemical substances and disease-causing microbes from contaminated and wastewater.

A silica-based ammonium molybdophosphate (AMP/SiO2) was successfully applied to remove Cs(I) from radioactive waste water in our previous study. The structure characterization of irradiated AMP/SiO2 was carried out by X-ray diffraction (XRD). The effect of the initial concentration of metal ions and acidity concentration for removal Cs(I) by irradiated AMP/SiO2 were investigated. No obvious difference was observed for AMP/SiO2 with 300 kGy absorbed dose from the XRD patterns, except the slightly shift of (110) peak toward a small angle. Relatively large distribution coefficient (8×103cm3/g) of
