Nanocomposite materials containing graphene oxide have attracted tremendous interest as catalysts and adsorbents for water purification. In this study, mesoporous titanosilicate/reduced graphene oxide composite materials with different Ti contents were employed as adsorbents for removing bisphenol A (BPA) from water systems. The adsorptive interaction between BPA and adsorption sites on the com...

Functionalized magnetic adsorbents (FMAs) were synthesized by a facile and surfactant-free one-pot solvothermal approach, using iron(III) chloride hexahydrate as the precursor, ethylene glycol as the reducing agent, ammonium acetate, and EDTA-2Na as an electrostatic stabilization agent. The self-assembly process of the functionalized magnetic adsorbents has been investigated and a plausible mec...

Bioethanol is considered to be the most optimistic biofuel. Hydrated ethanol with more than 2% (v/v) of water is not completely miscible with gasoline, so complete dehydration of ethanol is required. Distillation alone cannot concentrate ethanol beyond its azeotropic point so various other methods are used to concentrate ethanol to completely anhydrous state in short span of 93-99.80% (w/w) eth...

An unusual ceria dispersion was achieved by using the confined space between template and silica walls in as-prepared mesoporous silica, for the first time. The new adsorbents exhibit high adsorptive desulfurization activity and, more importantly, excellent stability and reusability, which is impossible to realize with conventional adsorbents.

The article provides an overview of the literature on the role of sorption detoxification using intestinal adsorbents (enterosorption method) in the multifaceted treatment of various diseases. The mechanism of action of adsorbents and their therapeutic effects are presented. We emphasized that intestinal adsorbent Enterosgel is a modern, effective, and safe detoxifying agent.

BACKGROUND Removal of mercury from aqueous environment has been highly regarded in recent years and different methods have been tested for this purpose. One of the most effective ways for mercury ions (Hg(+2)) removal is the use of modified nano porous compounds. Hence, in this work a new physical modification of mesoporous silica (SBA-15) with 1, 3, 5 (Trithiane) as modifier ligand and its app...

This study reviews the use of agricultural and agro-processing industry wastes as metal adsorbents from wastewater. Modified materials displayed better adsorption capacity and capability of some was comparable with that of commercial activated carbons and synthetic resins. Agricultural wastes are low-cost adsorbents and can be viable alternatives to activated carbon for treatment of metal-conta...

Experiments are described which confirm the observation of Gonzalez and Armangué that heterogenetic extracts can be made antigenic by adsorption to inorganic materials. With fractions of the original extracts from which a part of inactive material had been removed no such enhancement was observed, whereas with foreign protein an activation was still possible. Carbohydrate preparations behaved s...

302 This chapter gives a detailed description of the adsorbents manufactured by MACHEREY-NAGEL for coating of TLC plates. Especially for quantitative investigations, however, we recommend our ready-to-use layers with these adsorbents, since production of high-quality homogeneous layers for reproducible separations requires intense practical experience in coating techniques, which today is not a...
