Abstract

It is critical to synthesize adsorbents that are highly effective, affordable, highly selective, and excellently recyclable to remove refinery wastewater contaminants. Natural zeolites hold great promise for purifying water that contains heavy metals and organic pollutants, which is a typical representative of refinery wastewater effluents. In this work, a natural Egyptian zeolite ore was investigated as an adsorbent for refinery wastewater treatment applications. X-ray diffraction (XRD), X-ray fluorescence (XRF), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), Fourier transform infrared spectroscopy (FTIR) and Brunauer–Emmett–Teller (BET) analytical characterization techniques were used to characterize the zeolite ore. Batch adsorption tests were then conducted to investigate the removal efficiency of this zeolite for benzene (Bz) and strontium (Sr), two representative organic pollutants and heavy metals, respectively. This zeolite ore showed maximum adsorption capacities of 492.5 and 1700 mg/g for Sr and Bz, respectively. The Baudu isotherm model was found to be the best fit model in the case of Sr, whereas the Bz Langmuir–Freundlich and Sips models resulted in the highest R² value. Very fast kinetics were observed, and the equilibrium times were estimated to be 10 and 20 min for Sr and Bz, respectively. The current investigation showed that this layered Egyptian zeolite ore can be very promising for refinery wastewater treatment applications. An adsorbent is used to remove pollutants from refinery wastewater.

期刊介绍： Chinese Journal of Analytical Chemistry(CJAC) is an academic journal of analytical chemistry established in 1972 and sponsored by the Chinese Chemical Society and Changchun Institute of Applied Chemistry, Chinese Academy of Sciences. Its objectives are to report the original scientific research achievements and review the recent development of analytical chemistry in all areas. The journal sets up 5 columns including Research Papers, Research Notes, Experimental Technique and Instrument, Review and Progress and Summary Accounts. The journal published monthly in Chinese language. A detailed abstract, keywords and the titles of figures and tables are provided in English, except column of Summary Accounts. Prof. Wang Erkang, an outstanding analytical chemist, academician of Chinese Academy of Sciences & Third World Academy of Sciences, holds the post of the Editor-in-chief.
