“…The intermediates iron produced such as Fe 2+ , Fe 3+ , their hydroxides are thermodynamically unstable and much active. These also contributes to the catalytic activity [61][62][63][64][65]. Therefore, the radicals react with methylene blue resulting in dye degradation [34,50,60].…”

Green synthesized metallic nanoparticles are environmentally friendly, bio-compatible, and highly stable. The aim of this study was to synthesize iron nanoparticles (FeNPs) from FeCl 3 solution using aqueous leaf extracts of Galinsoga parviflora (Gp), Conyza bonariensis (Cb) and Bidens pilosa (Bp) and use them in degradation of methylene blue dye. The iron nanoparticles were characterized using UV-Vis spectrophotometer, FT-IR spectrophotometer, X-ray Fluorescence (EDXRF), X-ray diffractometer (XRD), and scanning electron microscope (SEM). Phytochemical screening for presence of secondary metabolites revealed presence of phenolics, phytosterols and flavonoids. The total phenolic and flavonoid content in Galinsoga parviflora, Conyza bonariensis and Bidens pilosa leaf extracts were 57.67 ± 1.27, 117.13 ± 0.03, 126.27 ± 0.013 mg Gallic Equivalent/g of Dry Weight (mg GAE/g DW) and 39.00 ± 0.56, 45.50 ± 0.59, 33.13 ± 0.81 mg Rutin Equivalent/g of Dry Weight (mg RE/g DW) respectively. The UV-Vis spectrum of FeCl 3 had a shoulder at 320 nm, which disappeared upon addition of G. parviflora, C. bonariensis and B. pilosa extracts confirming formation of iron nanoparticles. Evaluation of iron content of the synthesized nanoparticles revealed that the iron content in G. parviflora, C. bonariensis and B. pilosa extracts was 51, 47 and 44% respectively. XRD data revealed presence of a large amorphous coating that masked iron peaks, though 2 theta values observed have been reported to be of iron oxides. Methylene blue degradation studies revealed that CbNPs, BpNPs and GpNPs synthesized were good biocatalysts as they degraded the dye by 86, 84.3 and 92% respectively. Therefore, green synthesized iron nanoparticles is cost effective and environmentally safe in providing insight in the environmental removal of dyes.

“…Dye pollutants are the major sources of environmental pollution caused by various industries especially textile, cosmetic, leather, printing, paper, chemical paint, pharmaceutical, food and varnish industries [1]. Discharge of textile wastewater into the streams does not only affect the aquatic lives being having various metals and chlorides but also it seems that the presence of very small amounts less than 1 ppm for some dyes in water is undesirable for any use [2]. The stable and complicated structure of dyes makes a greater difficulty in the process of degradation of these dyes when present all kind of a complex matrix not only in textile wastewater but also in all industry wastewater [3].…”

Recently, the world has directed to find environmentally friendly and clean materials to be used to treat wastes difficult to treat in the traditional way such as dyes. The object of this study was to synthesize iron nanoparticles using black tea extracts in an environmentally sustainable method. Also, it was developed by supporting with bentonite, used to remove Eriochrome blue-black B dyes from synthesis wastewater of textile factory. From the results, it was noted that black tea leaf extract has reduced iron ions to iron nanoparticles at room temperature. Composite iron nanoparticles were characterized using Scanning Electron Microscope (SEM), and Atomic force microscopy (AFM) studies where the diameter of iron nanoparticles was less than 70 nm. This research shows that ferrous nanoparticles can be manufactured using black tea leaf extract as a reducing agent. It also shows better-supported nanoparticles than unsupported. The decolorization efficiency catalyzed BT-NZVI, B-BT-NZVI increased from (14%, 42%) to (48%, 68%) at 180 min of batch processes when the NZVI concentration was increased from 0.5 g/L to 2 g/L respectively.

Plant-mediated synthesis of iron oxide nanoparticles has been increasingly drawing attention due to its ecofriendly nature and cost effectiveness. The biosynthesis technique engages plant secondary metabolites such as alkaloids, flavonoids, saponins, phenols, proteins, carbohydrates, glycosides, quinine, steroids, and tannins as reducers and/or stabilizers in the process of forming nanoparticles thereby replacing hazardous chemicals known with physical and chemical methods of nanomaterial synthesis. Biosynthesis method of nano particles has helped to a great extent to overcome some drawbacks, such as high energy and space requirement as well as high cost and hazard associated with various known physical and chemical methods. This work reviewed the biosynthesis of plant mediated iron oxide nanoparticles and their applications in water and wastewater treatment. Much work has been done to explore the effective, safe and cheap method for the dye removal in recent years. However, in future, more methods need to be explored to study and check the removal of dyes from wastewater using plant-mediated iron oxide nanoparticles for safer, cheaper and more efficient performance.
