Adsorption kinetics and electrode processes

The Kinetics of Ethanol Fermentation Based on Adsorption Processes

Currently, the oil crisis and serious environmental problems related to fossil fuels have caused the world to turn more attention toward biofuels production, especially ethanol fermentation from biomass. An appropriate kinetic model of ethanol fermentation would be a powerful instrument for fermentation efficiency increase and process optimization. The well-known Monod equation has been widely ...

Electrode potential and selective ionic adsorption

Article history: Received 11 March 2009 Accepted 16 March 2009 Available online 20 March 2009 Communicated by V.M. Agranovich A simple description of the electrode potential based on the selective ionic adsorption is proposed. It is shown that if the adsorption–desorption coefficients entering in the Langmuir kinetic equation for the adsorption at the limiting surfaces are not identical, a diff...

Adsorption Processes

Adsorption is a fundamental process in the physicochemical treatment of municipal wastewaters, a treatment which can economically meet today's higher effluent standards and water reuse requirements. Activated carbon is the most effective adsorbent for this application. Expanded-bed contact systems permit most efficient use of granular carbon for waste treatment. The adsorption process is enhanc...

Adsorption Equilibrium and Kinetics of Lead Ion onto Synthetic Ferrihydrites

Batch experiments were conducted to study the adsorption behaviors of lead ion (Pb2+) onto ferrihydrites prepared using three different procedures which were characterized  by textural analysis (BET). The adsorption removal of Pb2+ by the three ferrihydrites (called FH-1, FH-2 and FH-3, respectively) were compared, and FH-3 shows fast adsorption kinetics as well as hig...
