Smart magnetic affinity adsorbents
… or ‘smart’ behaviour, current superparamagnetic adsorbents being employed both in small and large scale operations can be surface modified and improved by gaining dual functionalities. In this work, modification of M-PVA supports with polymer brushes of dual properties has been explored for their …

Chemical modification of activated carbon adsorbents
… modif fed using reactive chemicals to produce adsorbents of enhanced hydrophobic character which will also be resistant to surface oxidation that results from exposure to humid air ("ageing"). The intention was that modification would not disrupt the carbon pore structure. The adsorptive …

Characterisation of chromatography adsorbents for antibody bioprocessing
… diffusion resistance and binding capacity of the adsorbents. The ideal media would have high specificity, high mass transfer and binding capacity, low non-specific adsorption and ligand leakage, incompressibility, resistance to alkaline condition for sanitization, chemical stability and cost …

Magnetic adsorbents displaying switchable ion-exchange behaviour
Magnetic bioseparations based on non-porous adsorbents offer a low-fouling alternative to the porous materials required by conventional adsorbent separation techniques. Interest in magnetic bioseparations has been limited by the high cost of suitable magnetic absorbents. In this study a variety of …

Defluoridation of Water Using Silica Based Aluminum Coated Adsorbents
… and evaluated aluminum-coated silica-based adsorbents for effective and sustainable fluoride removal. Silica sand and microcrystalline silica served as base materials for coating with aluminum and combinations of aluminum, magnesium, calcium, and copper to create single, binary, and ternary …

Nanoclay-Based Solid-Amine Adsorbents for Carbon Dioxide Capture
… realistic flue gas of 10% CO2 and 90% N2, the adsorbents had essentially the same overall CO2 adsorption capacity indicating that the presence of nitrogen did not hinder the adsorption of CO2. Adsorption studies in pure CO2 at room temperature under pressure from 40-300 PSI were also conducted. …

Adsorbents as mitigators in the Transport System of Nitrogen in Soil
… It has been discovered that affordable adsorbents were found to be efficient, and interesting NH3removing methods have been tested to see whether they can be enhanced. Despite the threats posed by carbon and clay pollution and energy supply, carbon dioxide and adsorption could serve as a …

Development of novel adsorbents for the removal of emerging contaminants from water
… particles. The development of such novel hybrid adsorbents provides high binding capacity with organic contaminants along with high mechanical strength. Three different approaches were used to develop adsorbents by using two crosslinking agents (epichlorohydrin (EPI) and hexamethylene …

Manufacturing of agarose-based chromatographic adsorbents with controlled pore and particle size
Chromatography remains the most commonly employed method for achieving high resolution separation of large-sized biomolecules, such as plasmid DNA, typically around 150-250 nm in diameter. Currently, fractionation of such entities is performed using stationary phases designed for protein …

Metal -Organic Frameworks: Their Microwave Synthesis and Applications as Adsorbents for Preconcentration
MASS method provides us a simple and fast approach to quickly build a library of other new MOFs. In the third part, we demonstrate the syntheses of 14 new MOF materials based on the MASS method. Each has been tested by TGA to explore its sorption behavior with 4 different vapors. The structures for …

Investigation of Chitosan-based Adsorbents for Water Treatment, Pollutant Detection, and Adsorption Mechanism
… chitosan derivatives as effective biopolymer adsorbents for the uptake of model pollutants such as a typical organic dye (fluorescein), and a model heavy metal (Cu (II)) in aqueous media. For this purpose, a smart tweezer-like adsorbents with enhanced surface area were synthesized by grafting …

Preparation of CO2 adsorbents and techno-economic analysis for CO2 capture and utilization
… is one promising technology because CO2 adsorbents can provide an opportunity to capture CO2 with lower energy consumption, good stability, non-volatility, etc. Many adsorbents such as carbonaceous adsorbents, microporous organic frameworks (MOFs), amorphous microporous/porous organic …
