Background and Objectives: Water pollution with oil compounds causes the development of new technologies to eliminate oil pollution. The purpose of this study was to determine the efficiency of synthesized zinc oxide nanoparticles in the adsorption of oil from aqueous media.
Materials and Methods: In this laboratory study performed in the summer of 2019, zinc oxide nanoparticles were used as adsorbent to remove oil pollution from wastewater. The adsorbent specifications were determined using XRD, FTIR, FESEM and ICP analysis. Adsorption tests were discontinuously done using laboratory solutions containing oil. The optimum conditions for adsorption was examined through changing facors affecting adsorption such as the concentration of the contaminant, the contact time and the amount of adsorbent at different levels. A completely randomized block design was used for data processing.
Results: Adsorption rate was 74.1% and fixed after 20 minutes. The highest adsorption was observed at pH=7 at 85.27% and the lowest value was observed at pH=9 at 66.90%. The adsorption rate of zinc oxide nanoparticles at 1.5 g/l was 79.90% with a significant difference higher than the other concentrations. Finaly, the rate of oil adsorption in 100 mg/l concentration was 83.50% with a significant difference with the other concentrations. The adsorption of oil by zinc oxide nanoparticles was consistent with the Freundwich model (R2=0.99).
Conclution: Zinc oxide nanoparticles adsorbent has a high efficiency in adsorbing oil from wastewater and can be used to remove oil pollution.
Key words: Oil pollution, Adsorption isotherm, Zinc nano oxide, Factors affecting adsorption
