Adsorption of Crystal Violet Dye onto Tamarind Seed Powder
The present investigation describes adsorption of crystal violet dye from its aqueous solution onto tamarind (Tamarindus indica) fruit shell powder. Initial concentration, agitation speed and pH with various temperature have been studied, in which pH was

Adsorption isotherms of charged nanoparticles [PDF]
We present theory and simulations which allow us to quantitatively calculate the amount of surface adsorption excess of charged nanoparticles onto a charged surface. The theory is very accurate for weakly charged nanoparticles and can be used at physiological concentrations of salt.

Adsorption and removal of direct red 31 by Cu-MOF: optimization by response surface
Cu(PABA) is a Cu-based MOF material assembled from Cu2+ and the organic ligand p-aminobenzoic acid (PABA). Cu (PABA) was synthesized by a solvothermal method, characterized and applied to the adsorption of direct red 31 dye (DR-31). The effects of pH, DR-

Adsorption-induced surface normal relaxation of a solid adsorbent [PDF]
We investigate adsorption of a gas on the flat surface of a solid deformable adsorbent taking into account thermal fluctuations and analyze in detail the effect of thermal fluctuations on the adsorbent deformation in adsorption.

Role of Sorption Isotherms in the Analysis of Coupled Heat and Mass Fluxes in Porous Media [PDF]
The aim of this work is to show the importance of the sorption isotherms in the study of the heat and mass fluxes in unsaturated porous media. General forms of the heat and mass fluxes are presented in terms of experimentally accessible quantities.

The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.

Review of adsorption isotherms models
Because of its ease of use, affordability, effectiveness, and environmental friendliness, adsorption phenomenon is a widely used separation technique in wastewater treatment and environmental remediation. In a process known as an adsorption isotherm, the
