Application of adsorbents modified by nanoparticels
Original language description
Phyllosilicates are a promising group of materials since they are native, nontoxic, and applicable in numerous industrial sectors. Phyllosilicates can be used as carriers of photoactive, degradable, antibacterial, or fungicidal nanoparticles. They are efficient adsorbents of non-degradable pollutants due to their (e.g.) high specific surface area, chemical and mechanical stability, various structural and surface properties and higher cation exchange capacity. On the other hand, sorbent separation can be associated with substantial technological problems, mainly when the sorbent particles are of a very small size. However, the adsorbent can be modified by magnetically iron oxide micro/nanoparticles to facilitate removing the adsorbents from the solution - by using a magnet or magnetic field. The magnetically modified materials in this study were prepared from two montmorillonites and Ghassoul (a unique mixture of stevensite and sepiolite) using the microwave-assisted method of magnetic particle preparation. The adsorption of Sr2+ ions from water solution was studied. The experimental data were fitted by adsorption isotherms (Langmuir, Freundlich, and Sips). Results showed that the adsorption could be fitted by the Sips adsorption isotherm and, hence, the ion-exchange mechanism occurred. The presence of magnetic iron particles on the adsorbent surface does not always decrease the maximum adsorption capacity. The adsorption capacity depends on the type of clay and the way of adsorbent preparation.
