Water adsorption—quantum chemical approach
Electrochimica Acta, 1989The chemisorption of a single water molecule on the Cu, Ag, Au and Zn, Cd, Hg low index faces and of the (H2O)n associates (n = 2−5) on Ag(111) and on a close-packed mercury surface has been investigated by CNDO method together with geometrical optimization of the atom positions.

Aerodynamic Adsorption of Permeable Chemical Protective Suit
AIHAJ, 2001A new laboratory apparatus and method were developed to test the protective ability of a permeable chemical protective suit (PCPS). The key features of this method are using a wind tunnel system and an aerodynamic model that could incorporate the complicated flow pattern around the protective clothing.

CO2 adsorption on chemically modified activated carbon
Journal of Hazardous Materials, 2013CO2 adsorption capacity of a commercial activated carbon was improved by using HNO3 oxidation, air oxidation, alkali impregnation and heat treatment under helium gas atmosphere. The surface functional groups produced were investigated by diffuse reflectance infrared Fourier transform spectrometer (DRIFTS).

Adsorption of Antimony by Bagasse Fly Ash: Chemical Modification and Adsorption Mechanism
Water Environment Research, 2016ABSTRACT: Modification of bagasse fly ash (BFA) and the adsorption mechanism of antimony (Sb) by modified BFA were studied. It was found that BFA grafted with acrylic acid (BFAG) and BFA treated with hydrochloric acid (BFA/HCl) led to a decrease in the pH of the zero point of charge (pHzpc) of the adsorbents.

International Journal of Biological Macromolecules, 2015
Biosorption of Cu(II), Co(II) and Fe(III) ions from aqueous solutions by rice husk, palm leaf and water hyacinth was investigated as a function of initial pH, initial heavy metal ions concentration and treatment time. The adsorption process was examined by two adsorption isotherms: Langmuir and Freundlich isotherms. The experimental data of biosorption

Chemical pretreatment for activated‐carbon adsorption
Journal AWWA, 1981Organic substances from five different sources were effectively removed from water by coagulation. The effectiveness was related to the dosage of coagulant relative to the amount of organic matter present, the inorganic composition of the water, and the type of organic matter present.

Chemical Collection, Refinement, and Adsorption Beacon
2019 IEEE Sensors Applications Symposium (SAS), 2019The ability to perform in-situ water quality measurements allows the turnaround time for evaluation to drop from days to minutes compared to off-site laboratory analysis. This reduces the total cost of the data collection effort and results are obtained immediately.

Chemical-Physical Mechanisms of Adsorption for Blood Purification
2023The removal of soluble toxins from blood is necessary in patients with severe kidney failure. The majority of blood purification techniques are based on the use of semipermeable membranes, such as for dialysis treatment. But, whenever there is the need to remove small soluble molecules from blood, the use of such purification techniques may exhibit ...

Simulated water adsorption in chemically heterogeneous carbon nanotubes
The Journal of Chemical Physics, 2006Grand canonical Monte Carlo simulations are used to study the adsorption of water in single-walled (10:10), (12:12), and (20:20) carbon nanotubes at 298K. Water is represented by the extended simple point charge model and the carbon atoms as Lennard-Jones spheres.
