Estimation of Specific Surface Area using Langmuir Isotherm Method [PDF]

open access: yesJournal of Applied Sciences and Environmental Management, 2011
A comparison of four widely used linear equations of the Langmuir types of isotherm (The Langmuir Type 1, 2, 3 and 4 ) were examined in an experiment using dye sorption onto derived acid and salt treated Fish Activated Carbon (H3PO4-FAC and ZnCl2-FAC ...

Thermal rarefied gas flow investigations through micro/nano backward-facing step : Comparison of DSMC and CFD subject to hybrid slip and jump boundary conditions [PDF]

open access: yes, 2014
This paper evaluates the suitability of a newly developed hybrid “Langmuir-Maxwell” and “Langmuir-Smoluchowski” slip/jump boundary conditions in the Navier-Stokes-Fourier equations for nano/micro backward-facing step geometry flow which experiences ...

Adsorção de fósforo em frações argila na presença de ácido fúlvico Phosphorus adsorption by clay fractions in the presence of fulvic acid

open access: yesRevista Brasileira de Ciência do Solo, 2010
Os ácidos orgânicos podem ser adsorvidos aos coloides do solo, favorecendo maior disponibilidade de P às plantas. Por meio de isotermas, avaliou-se a influência de ácido fúlvico (AF) sobre a adsorção de P na fração argila de dois Latossolos Vermelhos ...

Competitive adsorption of p-hydroxybenzoic acid and phenol on activated carbon : experimental study and modelling. [PDF]

open access: yes, 2013
The competitive adsorption of phenol and p-hydroxybenzoic acid (4HBA) has been investigated on activated carbon (AC) for a wide range of concentrations under unbuffered conditions. The results show a preferential adsorption of 4HBA which can be explained
