Natural dyes have been used from ancient times for multiple purposes, most importantly in the field of textile dying. The increasing demand and excessive costs natural dye extraction engendered discovery synthetic petrochemical compounds. Nowadays, they are dominating market, with nearly 8 × 105 tons produced per year due to their wide range color pigments consistent coloration. Textile industries consume huge amounts water dyeing processes, making it hard treat enormous quantities this hazardous wastewater. Thus, harmful impacts when discharged non-treated or partially treated forms environment (air, soil, plants water), causing several human diseases. In present work we focused on dyes. We started by studying classification which depended nature manufactured fiber (cellulose, protein dyes). Then, mentioned characteristics dyes, however, more negative ecosystem (soil, plants, air) humans. Lastly, discussed applied physical, chemical biological strategies solely combination wastewater treatments. Additionally, described newly established nanotechnology achieves complete discharge decontamination.

The primary, most obvious parameter indicating water quality is the color of water. Not only can it be aesthetically disturbing, but also an indicator contamination. Clean, high-quality a valuable, essential asset. Of available technologies for removing dyes, adsorption used method due to its ease use, cost-effectiveness, and high efficiency. process influenced by several parameters, which are basis all laboratories researching optimum conditions. main objective this review provide up-to-date information on studied influencing factors. effects initial dye concentration, pH, adsorbent dosage, particle size temperature illustrated through examples from last five years (2017-2021) research. Moreover, general trends drawn based these findings. removal time ranged 5 min 36 h (E = 100% was achieved within 5-60 min). In addition, nearly 80% efficiency with just 0.05 g adsorbent. It important reduce (with Φ decrease E 8-99%). Among dyes analyzed in paper, Methylene Blue, Congo Red, Malachite Green, Crystal Violet were frequently studied. Our conclusions previously published literature.

Green Synthesized of Ag/Ag2O Nanoparticles Using Aqueous Leaves Extracts of Phoenix dactylifera L. and Their Azo Dye Photodegradation

Membranes, Journal Year: 2021, Volume and Issue: 11(7), P. 468 - 468

Published: June 25, 2021

In this study, silver/silver oxide nanoparticles (Ag/Ag2O NPs) were successfully biosynthesized using Phoenix dactylifera L. aqueous leaves extract. The effect of different plant extract/precursor contractions (volume ratio, v/v%) on Ag/Ag2O NP formation, their optical properties, and photocatalytic activity towards azo dye degradation, i.e., Congo red (CR) methylene blue (MB), investigated. X-ray diffraction confirmed the crystalline nature NPs with a crystallite size range from 28 to 39 nm. Scanning electron microscope images showed that have an oval spherical shape. UV–vis spectroscopy direct bandgap 2.07–2.86 eV indirect 1.60–1.76 eV. Fourier transform infrared analysis suggests synthesized might be stabilized through interactions -OH C=O groups in carbohydrates, flavonoids, tannins, phenolic acids present Interestingly, prepared high catalytic degradation for CR dye. was monitored spectrophotometrically wavelength 250–900 nm, decolorization efficiency (84.50%) obtained after 50 min reaction. As result, use extract offers cost-effective eco-friendly method.
