Removal of Reactive Blue 19 From Aqueous Solution Hollow NANO Silica Coated with Tio2

Structural control of nanoparticles is an effective method for modify the properties of colloidal particles. Especially raspberry-like particles have a hierarchical architecture which are providing applications such as drug delivery, separation and catalysis. In raspberry-like particles large sphere-shaped particles (host) are coating with smaller sphere-shaped ones (guest). On the other hand, because of their well-defined morphology, low density, large surface area and surface permeability hollow materials are having some interest about their applications in adsorption, catalysis and controlled release. It is simple to establish hollow particles into raspberry-like particles which are formed from host particles and guest ones by assemble hollow host particles or removing host particles later. The problem of the water pollution is increasing with the fast expansion in industries. Industries use 70% of the accessible fresh water and that’s why they produce a huge amount of wastewater and demand on clean water is rising. Industrial waste water contains toxic particles such as dyes, pesticides, organic chemicals and surfactants which are threat to aquatic life and cycle. Development in nanoscience and technology provide solutions to some of this problem and these problems have been reduced by using nanoparticles. Therefore, in the present study, the dye removal capability of titanium coating hollow nano silica particles was investigated. The effect of several parameters such as pH, adsorbent concentration, adsorbent size and temperature were studied by using Box Behnken design and adsorption mechanisms were evaluated.
