Zr-based metal-organic frameworks (Zr-MOFs) are emerging as potential adsorbents for removing nitrogen contaminants in fuel and wastewater. Functionalized Zr-MOFs exhibited superior indole (IND) adsorption capacity than the original MOF, but the activity of the multiple adsorption sites has not been discussed.

The present objective of this work is to find photoactive materials capable of facilitating visible light-driven redox reactions between CO2 and H2O. Our research is primarily focused on the incorporation of nitrogen (N) into the crystal lattice of titanium dioxide (TiO2) and its deposition onto Fe-MIL-88B to improve light absorption properties, minimize recombination of photo-generated electron-hole pairs, and increase CO2 adsorption capacity.

According to the batch experiments, the adsorption isotherms and the adsorption kinetics for these mesoporous materials are well fitted with the nonlinear Langmuir model and the nonlinear pseudo-second-order model, respectively. Among them, CuFe2O4 powder showed the best phosphate adsorption performance with the maximum P adsorption capacity of 27.49 mgP g-1 , which can be assigned to the highest surface area and the high pH value at its point of zero charge.

In this study, the objective was to employ experimental design in order to optimize the efficiency of diesel oil removal from water using activated carbon sourced from rambutan peel. A central composite design was utilized to investigate the impact of contact time, adsorbent dosage, initial oil concentration, and pH on both the removal efficiency and oil adsorption capacity across 30 different experimental designs.

The study aims to assess the diesel oil adsorption capacity of activated carbon derived from rambutan peel, a prevalent agricultural by-product in Vietnam. The adsorption process will be investigated using various adsorption isotherms (Langmuir, Freundlich, Temkin, Dubin-Radushkevich), adsorption kinetics (pseudo-first order and pseudo-second order).

In ebook "Factors affecting the removal of ammonia from air on carbonaceous materials: Investigation of reactive adsorption mechanism" new carbon-based materials are prepared and tested for ammonia adsorption at ambient conditions. Characterization of the adsorbents’ texture and surface chemistry is performed before and after exposure to ammonia to identify the features responsible for high adsorption capacity and for controlling the mechanisms of retention.

In this work, the hydrogels based on polyvinyl alcohol and chitosan were prepared. The glyoxal was used as a crosslinker with the aim of forming the three-dimensional network for the structure of these hydrogels. The adsorption capacity of the hydrogels for Cr(VI) ions was investigated with the various concentrations of glyoxal.

The ZnO/activated carbon nanocomposites are a potential adsorbent for treating polluted water. The effect of the mass ratio of molten ZnCl2 and rice husks, pyrolysis temperature on the characteristics and methylene blue (MB) adsorption capacity were charaterized. The adsorption isotherm and kinetics of the organic dye MB on the prepared ZnO/activated carbon were also thoroughly investigated.

Keramzite gravel is widely used in construction and agriculture. Keramzite is used as material to produce light-weight concrete and fixed bed for the growing vegetables. This material is now known as a completely new and cheap absorbent material. Surprisingly, the adsorption capacity of the reactive dyes on the Keramzite gravel has been successful and is the precondition for the production of other gravel particles with higher toxicity.

Waste from Jackfruit has little economic value and often causes serious environmental problems. The conversion of jackfruit waste will help reduce waste treatment costs, provide a potential source of raw materials for the activated carbon (AC) and increase economic value. In this study, the ACs from the Jackfruit shell and pulp were synthesized by microwave assistance for removing organic dyes.

Ciprofloxacin (CIP) is a second generation fluoroquinolone and is widely used in the treatment of bacterial infectious diseases in humans and animals. When released into the environment, CIP is quite stable in water and less biodegradable, so the concentration of CIP in environmental water is relatively high compared to other antibiotics.

The main aim of this investigation was to develop a low-cost solution to remove trace metals from the aqueous phase using biochar. This study investigated (i) the effect of giant reed-based biochar produced at varying temperatures in the treatment of aqueous solutions polluted with lead; and (ii) how the production of biochar at different temperatures affected its adsorption capacity for lead from the aqueous phase.

Deploying two salts in hydrophobic interaction chromatography can significantly increase dynamic binding capacities. Nevertheless, the mechanistic understanding of this phenomenon is lacking. Here, we investigate whether surface tension or ionic strength govern dynamic binding capacities of the chromatographic resin Toyopearl Butyl-650 M in dual salt systems.
