Abstract

A mathematical model on carbon coated monolith using the linear driving force model is develop. The computer program is writted in MATLAB and simulation using data from [4] for cell density 200 cpsi was used to studies the effect of different variables on breakthrough profiles. The result showed that the breakthrough curve of the monolith is very sharp. Because of its an open structure and lower pressure drop, monolith is an attractive alternative internals for separation.Keywords: Adsorption, modeling, simulation, carbon coated monolith, breakthrough

Abstract

The kinetics and mechanism of cadmium and zinc adsorption on palm kernel shell based activated carbons (PKSAC) have been studied. A series of batch laboratory studies were conducted in order to investigate the suitability of palm kernel shell based activated carbon (PKSAC) for the removal of cadmium (cadmium ions) and zinc (zinc ions) from their aqueous solutions. All batch experiments were carried out at pH 7.0 and a constant temperature of 30+-1C using an incubator shaker that operated at 150 rpm. The kinetics investigated includes the pseudo first order, the pseudo-second order and the intraparticle diffusion models. The pseudo-second order model correlate excellently the experimental data, suggesting that chemisorption processes could be the rate-limiting step.Keywords: adsorption, cadmium, kinetics, palm kernel shell, zinc
