Modeling of Experimental Adsorption Isotherm Data
Adsorption is considered to be one of the most effective technologies widely used in global environmental protection areas. Modeling of experimental adsorption isotherm data is an essential way for predicting the mechanisms of adsorption, which will lead to an improvement in the area of adsorption science. In this paper, we employed three isotherm models, namely: Langmuir, Freundlich, and Dubin...
متن کاملMultiscale estimation of the Freundlich adsorption isotherm
Adsorption plays an important role in water and wastewater treatment. The analysis and design of processes that involve adsorption rely on the availability of isotherms that describe these adsorption processes. Adsorption isotherms are usually estimated empirically from measurements of the adsorption process variables. Unfortunately, these measurements are usually contaminated with errors that ...

In this research by equilibrium adsorption isotherms of vitamin B2 (Ribo Flavin) on carbon nano-tubes having the multi wall through several discontinues method has been studied.with the help of spectro photometer (UV / VIS) adsorption chart based on the wavelength of vitamin B2 has been obtained, and the relevant graph is plotted .by considering factor of concentration, the concentration necess...
متن کاملIsotherm Equation for Water Vapor Adsorption onto Activated Carbon
A simple isotherm model has been developed for the type-5 equilibrium adsorption systems by considering the effects of both primary and secondary adsorptive sites. The model was applied to interpret experimental data describing water vapor adsorption capacities of four activated carbon adsorbents for relative vapor pressures from 0.0 to 0.95 and temperatures between 288 and 308 K. Good agreemen...
متن کاملHow Favorable Isotherm Is Favorable in Pressure Swing Adsorption?
A favorable isotherm open to the right to some extent is better than a linear isotherm to give shorter column height in pressure swing adsorption(PSA). We face to a problem how favorable isotherm is actually favorable in PSA operation. The purpose of this paper is to propose how to construct such a custom made isotherm which optimizes the PSA processes. The PSA mod...
