Graphene aerogel (GA) was synthesized by chemical reduction of graphene oxide (GO) using ethylene diamine as a reducing agent, which was then followed by a freeze-drying process. In this work, we produced GA by hydrothermal process followed by freeze-drying. The produced adsorbent was then deployed to study the TC adsorption process.

Harvesting microalgae by centrifugation and filtration is very costly, affecting technical and economical feasibility of downstream processing of algal biomas to bioproducts. Flocculation is a potential technique for recovery of algae biomass. Particularly, flocculation using magnetic nanoparticles offers high separation efficiency due to their high surface area and magnetic properties. I

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.

A thermochemical model was developed to calculate the H2 adsorption isotherm of the original Mg-MOF-74 framework, and its computationally designed isoreticular employing the adsorption energies and vibrational frequencies obtained from density functional theory calculations as input variables. The model reasonably replicates the experimental adsorption isotherm of the original framework at -196˚C within the pressure range up to 1 bar

In this work, a bimetallic Ni-Cu-BDC metal-organic framework system was developed via solvent thermal approach with using an organic ligand recycled from waste plastic. The physical properties of Cu-BDC and bimetallic Ni-Cu-BDC were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX) and N2 isotherms adsorption-desorption (BET).

Ebook "Introduction to food manufacturing engineering" provides basic food engineering knowledge for beginners. The discipline of food processing conforms with actual food manufacturing flows and thus is readily comprehensible, although food engineering has great diversity as the common principles of operations for most food manufacturing processes are covered. This volume therefore endeavors to initially embody food manufacturing flows and pays careful attention to quantitatively detailing and explaining the manufacturing operations involved from an engineering point of view.

In the present work, we report on the dye removal efficiency of Cobalt chromite, CoCr2O4 nanoparticles synthesized via the solvothermal method. The obtained CoCr2O4 nanoparticles demonstrated that the dye removal efficiency of CoCr2O4 nanoparticles could be enhanced by a reduction of size or improved water dispersibility.

This photocatalyst's high degradation efficiency is attributed to the synergistic effect of plasmon-induced visible light-harvesting due to Ag and enhanced adsorption and electronetransport properties due to rGO. It is found that the Ag-induced surface plasmon characteristics of the nanocomposites are sensitive to rGO concentration.

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.

Contaminants in plating wastewater are hard to remove, especially hexavalent chromium ions. This waste stream contains a large amount of Cr6+, a highly toxic metal, potential to cause cancer. To reduce this pollution, sludge from a supply water treatment plant (DWTS) has been used to make adsorbent.

In study "Using quail eggshell to treat methylene blue in aqueous solution", the raw quail eggshell powder (RQEP) was utilized as a cheap and environmentally friendly adsorbent to remove methylene blue (MB) from aqueous media under different conditions. The morphology of the prepared adsorbent was determined by scanning electron microscopy. The Langmuir and Freundlich isotherm models were used to model the adsorption data. The obtained results showed that the adsorption of MB on RQEP was well-fitted with the Freundlich model.

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.

The adsorption of Cu(II) ions from aqueous solution onto alginic acid has been investigated based on the establishment of a relationship among pH, conductivity and the concentration of metal ion. It was shown that the adsorption of this metal ion onto alginic acid followed the pseudo-second-order reaction and was conducted by ion exchange mechanism.
