This book presents some apparent divergences, that is, its content branches off in many
directions. This fact is reflected in the titles of the chapters and the methods applied in
discussing the problems of physical adsorption. It is not accidental. I aimed to prove that the
problems of physical adsorption, in spite of the ramified research fields, have similar or identical
roots. These statements mean that this book is 1) diverse, but still unified and 2) classical, but
still modern. The book contains monographs at a scientific level and some chapters include parts
that can be used by Ph.

The significant research in adsorption in the 70s through the 90s could be attributed to the discovery of many new porous materials, such as carbon molecular sieve, and the invention of many new clever processes, notably Pressure Swing Adsorption (PSA) processes. This evolution in adsorption research is reflected in many books on adsorption, such as the ones by Ruthven (1984), Yang (1987, 1997), Jaroniec and Madey (1988), Suzuki (1990), Karger and Ruthven (1992) and Rudzinski and Everett (1992).
The adsorption of γ-FeOOH for As (V) and As(III) could be competed by some other ion such as sulfate, ammonium and chloride. The high adsorption capability and good performance on other aspects make the γ-FeOOH nanorod a promissing adsorbent for the removal of As (V) and As(III) from the groundwater.
The adsorption of phenol over MCM-41 prepared from rice husk silica was investigated. MCM-41 material (RH-MCM-41) was synthesized using sodium silicate prepared from rice husk as a silica source and cetyltrimetylammoniumbromide (CTAB) as a surfactant with the following gel composition: 1SiO2: 0.106CTAB: 0.03NaOH: 150H2O. The obtained material was characterized by XRD and BET. RH-MCM-41 exhibits high surface area and highly ordered hexagonal mesoporous structures. The adsorption of phenol over RH-MCM-41 fit well to both Langmuir and Freundlich isothermers.
Investigations of kinetics of p-xylene deep oxidation on CuO/ -Al2O3 and CuO/ZSM-5 have been carried out. Specific surface area and pore size of catalyst samples as well as metallic state characteristics and catalytic properties of copper have been established. Catalyst CuO/ZSM-5 has been found to be more active than the first one, but it expressed lower stability because of less stable active form of Cu2+ on zeolite surface.
