An investigation on the capability of magnetically separable Fe3O4/mordenite zeolite for refinery oily wastewater purification.

摘要: Damage to the water resources and environment as a consequence of oil production use fossil fuels, has increased need for applying various technologies developing effective materials remove contaminates from oily wastewaters resources. One challenges an economic industrial wastewater treatment is separation reusability developed purifying agents. Development magnetic could potentially facilitate easier more Therefore, herein we have synthesised efficient easily recyclable Fe3O4/mordenite zeolite using hydrothermal process investigate its purification capability Kermanshah refinery. The was characterised XRD, FTIR, SEM, EDX, XRF BET analysis. XRD result showed that comprised sodium aluminium silicate hydrate phase [01-072-7919, Na8(Al6Si30O72)(H2O)9.04] cubic iron oxide [04-013-9808, Fe3O4]. Response Surface Method (RSM) combined with Central Composite Design (CCD) used identify optimum operation parameters pollutant removal process. effect pH, contact time amount on Chemical Oxygen Demand (COD), Biochemical (BOD) Nephelometric Turbidity Unit (NTU) were investigated. It found pH most significant factor influencing COD BOD but quantity influential turbidity capacity. conditions identified be 7.81, 15.8 min 0.52% w/w. results show regenerated can reused five consecutive cycles in petroleum wastes.
