Aqueous Phase Adsorption

This book covers theoretical aspects of adsorption, followed by an introduction to molecular simulations and other numerical techniques that have become extremely useful as an engineering tool in recent times to understand the interplay of different mechanistic steps of adsorption. Further, the book provides brief experimental methodologies to use, test, and evaluate different types of adsorbents for water pollutants. Through different chapters contributed by accomplished researchers working in the broad area of adsorption, this book provides the necessary fundamental background required for an academician, industrial scientist or engineer to initiate studies in this area. Key Features Explores fundamentals of adsorption-based separation Provides physical insight into aqueous phase adsorption Includes theory, molecular and mesoscopic level simulation techniques and experiments Describes molecular simulations and lattice-Boltzmann method based models for aqueous phase adsorption Presents state-of-art experimental works particularly addressing removal of "emerging pollutants" from aqueous phase

Adsorption of cephalexin.H2O on the surfaces of activated carbon and bentonite (which is provided locally in Iraq) was studied. The purpose of the study is searching for surfaces that are highly applicable of adsorption this compound which, taken in highly dozes, their results are some cases of poisoning. This study uses UV-Visible spectrophotometry to know the quantity of adsorption of these compounds on the employed surfaces at different conditions of temperature, pH, Ionic strength, quantity adsorbed, and particle Sizes. The shape of the isotherm obtained from the adsorption of cephalexin.H2O on bentonite and activated carbon was found to be comparable in all cases to the Freundlich and Langmuir equations was similar to S4-curve and L4- curve type according to Giles classification.The capacity of the adsorbents to adsorbing the cephalexin.H2O is in the following order: - Activated carbon
