چکیده :
Abstract For waste water treatment, There are numerous products that are already commercially available that contain solid metal and metal oxide nanoparticles (NPs), either embedded in a matrix or in solution. In this study, first, nanostructure metal oxide (NSMO) was synthesized by precipitation method using Zn(CH3COO)2.2H2O as a precursor to ethylene glycol. The reaction was followed by calcination at 450°C-550°C-650°C for 2 h in a furnace. Second, morphology of synthesized catalyst was characterized by SEM, XRD, UV-Vis and FT-IR techniques. Average size of ZnO nanostructures was determined 20 nm. Incorporation of starch to ZnO NPs was facilitated via sonochemistry. The ability of the modified NPs was investigated for removal of dye pollutant from aqueous solution.
