چکیده    Discharge of textile industry effluents, which contain large amounts of azo dyes, leads to many environmental problems and affects aquatic life due to its toxicity.[1]. in the present study, the use of activated carbon (ac) as a strong and widely used adsorbent for wastewater treatment of the textile industry was considered. the use of metal-organic framework (mof) structure to improve the performance of ac was also on the agenda. in this regard, the ac@mof composite was synthesized by simple solvothermal method using commercial activated carbon (cac) and mil-53(fe). the ftir, xrd, sem, and edx analyses were used to study the structure and morphology of ac@mof. in order to evaluate the performance of the cac, mil-53(fe) and ac@mof in dye removal process, direct red 23 (dr23) anionic dye was applied as a model contaminant. also, the effects of operational parameters on the adsorption process such as the initial dye concentration, adsorbent dosage, ph of solution and contact time, were investigated. the rate of dr23 removal under optimal conditions by commercial activated carbon and cac@mil-53(fe) composite was 50% and 99.9%, respectively. moreover, the maximum adsorption capacity was increased from 50 to 100 mg/g.

Abstract    Discharge of textile industry effluents, which contain large amounts of Azo dyes, leads to many environmental problems and affects aquatic life due to its toxicity.[1]. In the present study, the use of activated carbon (AC) as a strong and widely used adsorbent for wastewater treatment of the textile industry was considered. The use of metal-organic framework (MOF) structure to improve the performance of AC was also on the agenda. In this regard, the AC@MOF composite was synthesized by simple solvothermal method using commercial activated carbon (CAC) and MIL-53(Fe). The FTIR, XRD, SEM, and EDX analyses were used to study the structure and morphology of AC@MOF. In order to evaluate the performance of the CAC, MIL-53(Fe) and AC@MOF in dye removal process, Direct Red 23 (DR23) anionic dye was applied as a model contaminant. Also, the effects of operational parameters on the adsorption process such as the initial dye concentration, adsorbent dosage, pH of solution and contact time, were investigated. The rate of DR23 removal under optimal conditions by commercial activated carbon and CAC@MIL-53(Fe) composite was 50% and 99.9%, respectively. Moreover, the maximum adsorption capacity was increased from 50 to 100 mg/g.
