Abstract

Background and Aim: Petroleum products such as crude oil, Diesel and gasoline are the most commonly used in the world, which is the major pollutants of water. About 10 million tons of oil are used annually in the world. Therefore, the development of new technologies for the elimination and purification of oil pollution is essential. There are several methods for cleaning up oil pollution and its derivatives. In this research, Straw adsorbent as an organic one was used to remove Diesel oil from Wastewater. Materials and methods: The Straw characterization was firstly determined using the FT-IR analysis. Then the adsorption experiments were performed discontinuously using Diesel oil laboratory’ s solutions. Optimum adsorption conditions were obtained by changing the factors affecting adsorption including pH, initial concentration of contaminant, contact time and adsorbent amount on adsorption at different levels. The oil adsorption was determined by weighting method. Results: The highest adsorbent efficiency was observed in 15 minutes, which did not have any significant differences with other contact times (49. 85% absorbance, P<0. 05), and the lowest value was observed without any significant differences in 3 minutes (37. 19% absorption). The highest rate of adsorption was observed at pH =5, which had a significant difference with other pHs (87. 89% adsorption, P<0. 05) and the lowest percentage of adsorption was observed at pH = 9, which had no significant difference with other pHs (39. 04% absorption; P<0. 05). in The efficiency of the process in adsorbent dosage of 2 g/L was significantly higher than other amounts of adsorbent (51. 48% absorption, P<0. 05), and the lowest percentage of adsorption was significantly different from other values in 0. 25 g/L (38. 30%, P<0. 05). Also, according to the isotherm studies, the adsorption of Diesel oil by Straw adsorbent was fitted with both Freundwich and Langmuir models with R2 of 0. 99 and 0. 96 respectively. Conclusion: Therefore, it can be concluded that the Straw adsorbent, has a high efficiency in adsorption of Diesel from Wastewater and can be used in the treatment of industrial Wastewater.
