This paper presents the influence of different precursors on morphostructure zinc oxide nanoparticles used for impregnation polystyrene (PES) filters. Zinc were synthesized by a microwave and ultrasound-assisted hydrolytic method using (Zn(NO3)2-6H2O; ZnSO4-7H2O; Zn(CH3COO)2-2H2O) sodium hydroxide as nucleophilic agent. The resulting powders calcined at 550 °C 2 hours. Using Williamson-Hall XRD analysis, crystalline structure was determined, with average sizes 40 nm (ZnO_AZ_US_MAE), 35.6 (ZnO_SU_US_MAE) 36.4 (ZnO_AC_US_MAE). Morphological analysis SEM revealed shapes (polyhedral irregular plates) ranging from 47 to 127 powder obtained nitrate precursor, 43 63 prepared sulfate 42 89 acetate precursor. ATR FTIR spectroscopy confirm presence Zn-O bonds. In addition, BET showed that among three Ipowders precursors, ZnO_SU_US_MAE had highest surface area value 16.4381 ± 0.0146 m²/g an particle size 63.4671 nm, which confirmed analysis.
