Diversity of Synthetic Dyes from Textile Industries, Discharge Impacts and Treatment Methods

Applied Sciences, Journal Year: 2021, Volume and Issue: 11(14), P. 6255 - 6255

Published: July 6, 2021

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 history of colour is fascinating from a social and artistic viewpoint because it shows the way; use; importance acquired. use colours date back to Stone Age (the first news cave paintings); has contributed symbolic development civilizations. Colour been associated with hierarchy; power leadership in some them. advent synthetic dyes revolutionized industry; due their low cost; spread different industrial sectors. Although percentage coloured wastewater discharged by textile; food; pharmaceutical; cosmetic; paper industries; among other productive areas; are unknown; toxic effect ecological implications this into water bodies harmful. This review briefly surrounding discovery natural dyes. We summarise environmental impact caused discharge untreated or poorly treated bodies; which led physical; chemical biological treatments reduce units so as important physicochemical parameters. also focus on laccase utility (EC 1.10.3.2), for discolouration enzymatic treatment wastewater, before its bodies. Laccases (p-diphenol: oxidoreductase dioxide) multicopper enzymes widely distributed plants, insects, bacteria, fungi.

Biomass-Based Adsorbents for Removal of Dyes From Wastewater: A Review

Frontiers in Environmental Science, Journal Year: 2021, Volume and Issue: 9

Published: Dec. 9, 2021

Dyes, especially azo dyes contained in wastewaters released from textile, pigment, and leather industries, are entering into natural waterbodies. This results environmental deterioration serious health damages (for example carcinogenicity mutagenesis) through food chains. Physiochemical, membrane processes, electrochemical technology, advanced oxidation reverse osmosis, ion exchange, electrodialysis, electrolysis, adsorption techniques commonly used conventional treatment technologies. However, the limitations of most these methods include generation toxic sludge, high operational maintenance costs. Thus, technological advancements use to remediate effluents. Adsorption using nonconventional biomass-based sorbents is greatest attractive alternatives because their low cost, sustainability, availability, eco-friendly. We present reviewed up-to-date publications on for dye removal. Conceptualization synthesizing state-of-the-art knowledge characteristics, experimental conditions were also discussed. The merits various biosorbents reflected. maximum capacities synthesized order biomass type (algae, agricultural, fungal, bacterial, activated carbon, yeast, others). Surface chemistry, pH, initial concentration, temperature, contact time, adsorbent dose as well ways preparations materials affect biosorption process. Based average capacity, those arranged prioritized. best fit isotherms Freundlich Langmuir models) basic operating parameters removal retrieved. Which adsorbents have greater potential based uptake nature, cost-effectiveness, bulk mono multilayer behavior was including desorption cycles preparation operation implementation this technology forwarded.
