AB  - In this study, the adsorption behavior of silica adsorbents with different morphology and porosity has been examined in order to evaluate their use for the purification of wastewaters containing toxic environmental chemicals such as heavy metals and pesticide residues. Three different types of silica particles were investigated: (i) microporous silica core particles prepared by the hydrolysis and condensation of tetraethylorthosilicate (TEOS), (ii) mesoporous silica particles generated by the neutralization of highly basic sodium silicate solution and (iii) silica core-shell particles composed of mesoporous silica layers around dense cores. Monodispersed spherical silica particles produced from TEOS have a microporous structure but the lowest adsorption efficiency and adsorption capacity of both heavy metals and pesticides. Polydispersed silica particles of irregular shape prepared from highly basic sodium silicate solution exhibit a mesoporous structure and high efficiency for the removal of heavy metals and pesticides from aqueous solutions. Monodispersed core-shell particles composed of a microporous core and a mesoporous shell also have high adsorption efficiencies in both combinations. Moreover, silica particles can be easily functionalized with ferrite nanoparticles, which allow the magnetic separation of silica adsorbents from aqueous solutions.

AB  - The present work describes the synthesis of zinc ferrite nanoparticles by a chemical coprecipitation method and its surface modification with poly(diallyldimethylammonium chloride) (PDDA), tetramethylammonium hydroxide (TMAOH) and poly(ethylene glycol) (PEG). The effect of coating on the colloidal stability of obtained systems as well as the effect of modification procedure on the final characteristics of particles were studied. The unmodified and modified nanoparticles were characterized by X-ray diffractometry (XRD), scanning electron microscopy (SEM) and Raman spectroscopy. The particle size distribution and stability of these systems were investigated by dynamic light scattering (DLS) and zeta potential measurements. The results have shown the profound effect of the used modification procedure on colloidal stability of the investigated particles.
