Efficient and ecofriendly cellulose-supported MIL-100(Fe) for wastewater treatment

Abstract

In this manuscript, the successful utilization of an improved cellulose-supported MOF, MIL-100(Fe)@CMC, for the adsorption of lorazepam is reported.

A review of recent trends in the removal of emerging contaminants from wastewater using green adsorbents

“…The environmental sustainability of graphene oxide (GO) and reduced graphene oxide (rGO) as adsorbents was highlighted in a study [11], underscoring their potent efficacy in purging Pb (II) ions from wastewater. Their comparative analysis showcased high adsorption capacities, confirming the process as spontaneous and exothermic, with rGO outperforming GO in terms of capacity.…”

“…The valorisation of agricultural waste into effective adsorbents was showcased in a study [37], focusing on the removal of antibiotics using mango seed kernel-derived materials, illustrating a sustainable approach to pharmaceutical wastewater treatment. The application of metal-organic frameworks (MOFs) for the removal of benzodiazepines from wastewater was explored [11], revealing the high adsorption capacity and recyclability of a novel composite, indicating its potential for broader pharmaceutical contaminant removal. A novel adsorbent hydrogel [38] demonstrated significant potential in diclofenac sodium removal from water, emphasizing the effectiveness of chitosan-based materials in pharmaceutical waste management.…”

“…Among the plethora of wastewater treatment methodologies, adsorption stands out for its economic efficiency, straightforward design, minimal carbon footprint, and environmental sustainability [10]. This method is lauded for its operational simplicity and high potential for adsorbent regeneration, making it a paragon of ecofriendly technology [11]. In this context, the advent of non-conventional adsorbents, particularly biosorbents, marks a pivotal shift towards leveraging materials with exceptional adsorptive capabilities [12], environmental compatibility, and broad accessibility.…”

Metal–Organic Frameworks as Powerful Heterogeneous Catalysts in Advanced Oxidation Processes for Wastewater Treatment

“…Nevertheless, other studies have looked for alternatives to having free Fe-MOF to see if they could improve the existing Fe-MOF or use no-toxic dissolvent. Indeed, this was achieved and a clear example was the work of Taherzade et al [125], who immobilized MIL-100(Fe) in carboxymethylated cellulose (CMC). A great advantage of their synthesis was that the solvent used was water, so proving non-toxic solvents can be used, and it operated under non-severe conditions.…”

“…A great advantage of their synthesis was that the solvent used was water, so proving non-toxic solvents can be used, and it operated under non-severe conditions. The only drawback was the long drying time of the final product which was 7 h at a temperature of 60 • C. Despite this drawback, this synthesis is promising as it achieved better adsorption rates and was more efficient than MIL-100 (Fe) which was synthesized by the solvothermal method [125].…”
