Due to its importance water, a lot of research has been done in the field of nanotechnology for water purification. In this study, Nd-TiO2/PVP/bentonite nanocomposit was synthesized by three chemical compounds that had adsorption property. Microstructure of synthesis nanocomposite was investigated by XRD, SEM and FT-IR. The removal process of Cu2+ was performed by flotation of nanocomposite in the bulk of sample. The effective parameterswere investigated in removal process, such as: removal time, sample volume, amount of nanocomposite, pH and etc.The concentration 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. The photocatalytic activity of Nd-TiO2/PVP/bentonite nanocomposite will investigate under visible light irradiation.
