Abstract The global manufacturing sector heavily relies on the textile industry, yet widespread utilization of synthetic dyes within this has raised serious environmental apprehensions, notably regarding wastewater contamination. release untreated containing residual poses a significant risk to both aquatic ecosystems and human well‐being. In reaction issue, considerable efforts have been made develop efficient sustainable methods for removal from wastewater. This comprehensive review paper furnishes in‐depth literature information covering various aspects dyes, including their classification, toxicity effects, evaluation recent advancements in dye technology, emphasizing advantages, limitations, future potential. Various strategies are covered, physical, chemical, biological methods. Physical techniques like adsorption, filtration, membrane technologies contrasted with chemical approaches such as coagulation, precipitation, advanced oxidation processes. Biological include micro‐organisms, fungi, enzymes break down or metabolize compounds. Key considerations critical analysis efficiency, cost‐effectiveness, scalability each method. focuses enzyme breakdown (biological) adsorption (physical) color procedures, which currently considered most effective. It also proposes composite adsorbent, anticipating enhanced efficiency faster through technique.

The discharge of congo red dye into water sources by factories has been associated with a range health concerns, such as cancer, redness, skin irritation, and allergic reactions. As result, this research focused on the cost-effective straightforward production MgAl2O4 nanoparticles using Pechini sol–gel process. Subsequently, these were employed for successful photocatalytic decomposition dye. Moreover, extensive characterization fabricated was conducted through diverse methodologies, which included Fourier-transform infrared spectroscopy, ultraviolet–visible spectrophotometry, high-resolution transmission electron microscopy (HR-TEM), field-emission scanning (FE-SEM), powder X-ray diffraction (XRD). Furthermore, XRD analysis disclosed that average crystal size produced is 10.36 nm, their optical energy gap determined to be 3.71 eV. FE-SEM examination unveiled combination spherical disorganized structures 0.14 μm grain size. HR-TEM analysis, in turn, revealed composed minuscule particles an diameter 8.75 nm. maximum degradation 50 mL at concentration 25 mg/L reached 99.27% within 80 min pH 3. Additionally, findings confirmed consistent activity toward even after four cycles, thereby validating effectiveness reusability developed study.

Abstract Agricultural wastes are potential sustainable adsorbents since they available in large quantities, low-cost, and may require little or no treatment, some cases. In this study, several fruit peels, such as banana, orange, pomegranate, were collected from local markets prepared by a simple eco-friendly method used natural for the removal of both anionic (Reactive Red 120 (RR120), Reactive Black 5 (RB5), Remazol Brilliant Blue R (RBBR)) cationic Methylene (MB) dyes found wastewaters. Many industries, leather textiles, can release huge amounts synthetic into wastewater during dyeing processes. These one most important pollutants water pollution cause enormous damage to body also affect health organisms due their toxicity carcinogenicity. The search at same time efficient material wide variety is innovation work. peels washing, drying, grinding, finally sieving, under conditions. Porosometry (BET analysis), FTIR, SEM/EDS, XRD techniques characterize before after adsorption process. Factors affecting (adsorbent dosage, pH solution, initial concentration dyes, contact time, temperature) investigated. According results, terms effectiveness (natural) adsorbent materials, 5.0–6.0 g/L banana orange dry was sufficient remove near even more than 90% 2.0, 4.0 98% MB dye 9.0. Similar amount pomegranate had lower efficiency (50–70%), while still efficiently removed (98%) Moreover, process all cases better fit pseudo-second-order model, comparison pseudo-first-order model. isotherms, Freundlich model fitted equilibrium data, Langmuir others. Finally, study demonstrates viability reusing peel eight, four, five cycles, showing gradual reduction around 50% effectiveness. Graphical
