Abstract:
Due to its importance water, a lot of research has been done in the field of nanotechnology for waterpurification. In this study, Nd-TiO2/PVP/bentonite nanocomposit was synthesized by three chemical compounds that hadadsorption property. Microstructure of synthesis nanocomposite was investigated by XRD, SEM and FT-IR. The removalprocess of Pb2+ was performed by flotation of nanocomposite in the bulk of sample. The effective parameters wereinvestigated in removal process, such as: removal time, sample volume, amount of nanocomposite, pH and etc. Theconcentration of selected ion was monitored by using a flame-atomic absorption spectrometer. In the optimized condition,effect of interference ions was studied and according results, no evidence of interference was observed. Thephotocatalytic activity of Nd-TiO2/PVP/bentonite nanocomposite will investigate under visible light irradiation.
