Removal of toxic metals from wastewater by using Dendritic Fibrous Nanosilica (DFNS)

Abstract

Dendritic fibrous nanosilica (DFNS) is a notable invention in recent years. Due to the fibrous morphology; DFNS behaves differently for various applications in the area of catalyst, energy storage, solar energy harvesting and biomedical applications. The morphology of DFNS enhances the molecular loading on active sites of silica surface by avoiding blockage of the pores. Also high surface area of silica material gets better internal surface accessibility with controlled particle sizes, tunable pore size and pore volumes which improves stability of DFNS. In view of the advantages of DFNS material, the ability of this material at various applications mentioned above can be exploited in better way. Such molecules can be utilized with the atom economy of the molecules to deliver maximum efficiency of the particle size and structure. Hence to apply DFNS at large in most probable applications, still very keen research is required. Here for the current study the target is to synthesize DFNS with the wide adoptability by improving different properties and apply it for the removal of pollutants such as toxic metal ions specifically chromium (Cr+2) and mercury (Hg+2). Characterization of DFNS morphology has been detected by Scanning electron microscope (SEM) to apply for the current water treatment processes.
