Zeolites are porous aluminosilicates with a crystalline structure that contain a system of
interconnected chambers and channels. The geometrical parameters of zeolites are one of …

The traditional hydrothermal synthesis methods are mainly performed under batch
operation, which generally takes few days to weeks to yield a zeolite with the desired …

Five adsorbents based on fly ash treated with NaOH for the adsorption of cadmium ion from
aqueous solutions were investigated. The materials were characterized using scanning …

The initial characteristics of Romanian fly ash from the CET II Holboca power plant show the
feasibility of its application for the production of a new material with applicability in …

The experimental study investigates the feasibility of using two extensively waste
(wastewater treatment sludge and oak wood ash) as raw materials in the manufacture of …

Fly ash wastes (silica, aluminum and iron-rich materials) could be smartly valorized by their
incorporation in concrete formulation, partly replacing the cement. The necessary binding …

This study aimed to analyse the bioaccumulation of heavy metal ions in plants of
spontaneous flora. An urban area was established from which soil samples were taken and …

In this paper, synthetic metakaolin with fixed composition (Al2O3· 2SiO2) was produced by a
simple chemosynthetic route. The chemosynthetic metakaolin can eliminate the influence of …

Zeolites are aluminosilicates with a lattice structure consisting of tetrahedral AlO4 and SiO4
molecules. Due to the lattice structure of zeolites, there are many areas of use from …

Major changes of the environment are caused by the presence of pollutants in air, soil, and
wastewaters. From these, a major attention is accorded to the industrial wastewaters …
