Ab initio calculations based on the density functional theory were used. A cluster model of the faujasite zeolite structure (Al2Si22O66H36) with metal particles adsorbed above the aluminium centres was used. The NO and NH3 adsorption processes, individual and co-adsorption, have been studied over metal nanoparticles bound into zeolite clusters.
The properties of slag formed by municipal solid waste incineration were investigated. The possibility of their use to obtain composite cements with the mineral additives was established. The possibility to solve material and energy saving problems, as well as environmental pollution is demonstrated.
The article presents the research results of using different types of silicate minerals, their modified forms for sewage sorption treatment. Their physical and chemical properties, the mechanisms of action and sorption efficiency of the widespread natural minerals are characterized in this paper.
A review of literature concerning application of natural and modified zeolites for water and wastewater purification from inorganic (ionic) and organic pollutants is presented.
