wastewaters and soils, such as chemical precipitations, conventional coagulation, reverse osmosis, ion exchange, and adsorption on activated carbon [ 1 ]. Among these methods, adsorption appears to be the most widely used for the removal of heavy metals [ 2

them have similar limitations [ 8 ]. Amongst the numerous techniques of dye removal, the adsorption process is one of the effective processes that have been successfully employed for color removal from the wastewater [ 12 ]. Although activated carbon

intervening in the effectiveness of photodegradation is adsorption of pollutants on the photocatalyst surface. Many studies measured the adsorption and the kinetics of photodegradation of different compounds on TiO 2 photocatalyst, such as potassium

Introduction This paper ensues an earlier study [ 1 ] wherein adsorption isotherm measurements for methane on a Maxsorb II specimen of activated carbon were reported. They were obtained with a monotonically increasing uptake up

The histamine amount attached to the silica surface was obtained from the nitrogen amount determined by the Kjeldahl method [ 9 ]. The surface area, pore diameter, and pore volume of materials were obtained by using the nitrogen adsorption

compounds have reported undesired effects at trace concentrations [ 1 ]. PPCPs and their metabolite elimination channels in sewage treatment plants (STP) mainly include adsorption on biosolids, biodegradation, air-stripping and hydrolysis, and their removal

instance, the Pt–Au catalyst exhibits higher selectivity toward the partial hydrogenation of compounds with two C=C bonds than pure Pt [ 3 ]. The adsorption of hydrogen on the catalyst is an important step in hydrogenation reactions. While Pd and Pt adsorb
