Abstract
This review spotlights the transformative potential of spinel ferrite compositions in revolutionizing wastewater remediation, particularly in eliminating toxic dyes and heavy metals. With their versatile cubic structures and finely tunable compositions, spinel ferrites emerge as powerful catalysts capable of driving efficient photocatalytic and adsorptive processes. Spinel ferrites have demonstrated up to 99.5% degradation efficiency for methylene blue (MB) within 90 min and completely removed other dyes like methyl orange (MO) under optimal conditions. By honing in on the intricate role of metal ion variations within the spinel lattice, this review uncovers how these compositional tweaks dramatically enhance catalytic performance, optimize band gaps, and boost magnetic properties. The discussion emphasizes how compositional variations, such as doping with rare-earth metals, which increased dye degradation efficiency by 97.76 % in cobalt‑zinc ferrites. Beyond their lab-scale potential, we address the critical challenges of scaling these materials for real-world applications, including their reusability, long-term stability, and commercial viability. This comprehensive analysis underscores the promise of spinel ferrites as next-generation materials in the quest for sustainable and effective water purification.
期刊介绍:
The Journal of Water Process Engineering aims to publish refereed, high-quality research papers with significant novelty and impact in all areas of the engineering of water and wastewater processing . Papers on advanced and novel treatment processes and technologies are particularly welcome. The Journal considers papers in areas such as nanotechnology and biotechnology applications in water, novel oxidation and separation processes, membrane processes (except those for desalination) , catalytic processes for the removal of water contaminants, sustainable processes, water reuse and recycling, water use and wastewater minimization, integrated/hybrid technology, process modeling of water treatment and novel treatment processes. Submissions on the subject of adsorbents, including standard measurements of adsorption kinetics and equilibrium will only be considered if there is a genuine case for novelty and contribution, for example highly novel, sustainable adsorbents and their use: papers on activated carbon-type materials derived from natural matter, or surfactant-modified clays and related minerals, would not fulfil this criterion. The Journal particularly welcomes contributions involving environmentally, economically and socially sustainable technology for water treatment, including those which are energy-efficient, with minimal or no chemical consumption, and capable of water recycling and reuse that minimizes the direct disposal of wastewater to the aquatic environment. Papers that describe novel ideas for solving issues related to water quality and availability are also welcome, as are those that show the transfer of techniques from other disciplines. The Journal will consider papers dealing with processes for various water matrices including drinking water (except desalination), domestic, urban and industrial wastewaters, in addition to their residues. It is expected that the journal will be of particular relevance to chemical and process engineers working in the field. The Journal welcomes Full Text papers, Short Communications, State-of-the-Art Reviews and Letters to Editors and Case Studies
