The functional shape of a sorption isotherm is determined by underlying molecular interactions. However, doubts have been raised on whether the mechanism can be understood in principle from analyzing curves via range competing models. We shown recently that it possible to translate interactions rigorous statistical thermodynamics. aim this paper fill gap between thermodynamic theory and experim...

In this study adsorption of 1-chloro-4-nitrobenzene on single walled carbon nanotubes has been investigated.  The effect of contact time, pH, initial concentration of 1-chloro-4-nitrobenzene, adsorbent dosage and temperature on its adsorption has been carried out in order to find optimum adsorption conditions. Adsorption isotherms and related constants were also determined. Results showed that ...

Removal of fluoride ions was investigated using a new adsorbent of yttrium alginate biocomposite (YALG). Effect of various parameters such as pH, contact time, initial concentration of fluoride ions and temperature on the sorption capacity of adsorbent was studied. Performing a mathematical assessment of fluoride sorption, isotherm and kinetics models including Freundlich & Langmuir isotherms a...

We present the RUPTURA code (https://github.com/iraspa/ruptura) as a free and open-source software package (MIT license) for (1) simulation of gas adsorption breakthrough curves, (2) mixture prediction using methods like Ideal Adsorption Solution Theory (IAST), segregated-IAST explicit isotherm models, (3) fitting models on computed or measured data. The combination with RASPA enables computati...

In this study, it was aimed to prepare and analyze an environmentally friendly adsorbent because fluoride in water is important health threat affecting the whole world. ZnO doped chitosan produced for fluorine adsorption. The characterization of done by FT-IR, SEM-EDX analysis. effects pH, initial concentration, amount on adsorption were investigated. Langmuir Temkin isotherm models studied fou...
