Abstract:
Li+- and Na+-exchanged ZIF-67 was synthesized by a new one-step method of ion as-exchange technique and tested as CO2 adsorbents. As a comparison, the standard ion-exchange procedure was also carried out. The powder X-ray diffraction (XRD), scanning electronic microscope (SEM), particle size analyzer (PSD), and thermal gravimetry analysis (TGA) were used to investigate the effect of ion-exchange techniques on the structure of the materials. CO2 uptake of ZIF-67 ion exchanged by one-step method is much higher than that by the standard ion-exchange procedure. All of the adsorption isotherms show

Abstract:
The adsorption of several aromatic nitro compounds and the ion-exchange of heavy metal ions on electro-oxidized carbon fibres have been investigated using cyclic voltammetric and polarographic techniques. Electro-oxidation is performed by potentiostatic double pulse application. This procedure results in the generation of many functional —OH and —COOH groups with adsorptive and ion-exchanging properties.Multimolecular layers of adsorbed substances may be formed through a procedure of successive adsorption of the nitro-compound and electro-reduction to the corresponding amine, resulting in the

The interactions of cholestyramine with bile acids in aqueous buffer solutions were studied by in vitro adsorption experiments. Application of the Donnan theory, which is based on ion partitioning between two phases, indicates that the adsorption is an ion-exchange process--the bile acid anion displaces the chloride counter-ion of cholestyramine. Donnan considerations indicate that the bile acid in the resin phase exists in two forms, bound and unbound, but at higher Ceq the bound form is increasingly favoured. Since the concentrations of bound bile acid in the resin phase are above the critic

Reactions in semi-permeable layers include redox processes involving electron transfer, adsorption, ion-exchange and complexation reactions and precipitation/dissolution processes.

Abstract:
The presence of nitrate concentration in drinking water can cause high toxicity to the human body, being considered among the most important pollutant in the environment. Among the many methods available such as biological treatment, electrodialysis, reverse osmosis, adsorption, ion exchange, adsorption is the most used technique due to its low cost and simplistic design. Therefore, the aim of this paper was to study the retention of nitrate anion from high concentration aqueous solutions on a novel magnetic adsorbent obtained by pyrolysis of de-oiled microalgal biomass. The prepared adsorbent

Abstract:
Effects of three different reduction environments on the preparation of Cu(I)X and Cu(I)Y zeolites and their adsorption selectivities towards propylene were investigated. NaX and NaY zeolites were ion exchanged with ammoniacal copper solution before they were reduced with 1 h of ammonia flow, 2 h of ammonia flow, or 1 h of hydrogen flow. Results from inductively couple plasma indicated that there was an incomplete exchange between Cu+ and Na+, which may be from the limitation of this preparation method. The x-ray photoelectron spectroscopy results showed that all reduction methods provided the

Abstract:
Poly-,Per-fluorinated alkyl substances (PFAS) are versatile chemicals that were incorporated in a wide range of products. One of their most important use was in aqueous film-forming foams for fighting liquid fuel fires. PFAS compounds have recently been identified as potential environmental contaminants. In the United States there are hundreds of potential military sites with PFAS contamination. The ERDC designed and constructed a mobile treatment system to address small sites (250,000 gallons or less) and as a platform to field test new adsorptive media. The PFAS Effluent Treatment System (PE
