Electrochemical detection and removal of brilliant blue dye via photocatalytic degradation and adsorption using phyto-synthesized nanoparticles

Abstract

A sensitive electrochemical platform is sensing brilliant blue dye and monitors its removal from wastewater by degradation and adsorption processes.

A Review on Synthesis and Characterization of Copper Doped Zinc Oxide Nanocomposites

“…Older ancient facilities was equipped with enamourous nanoparticles in the form of "Bhasma" that was elaborated in ancient medicines, as this era developed the ancient processes of nanoparticles formation in modified methodology in bulk process [1,2]. Nanocomposites developed from metal implementation in various plant materials was largely introduced in long ago centuries, which was implemented as medicine in fever, cough, cancer treatment, arthritis, stomach pain and many more irregularities effecting animal and human health [3]. As era changes development in the fields of sciences with modified research has been occurred extensively by the leading routes of developments in the research fields [4].…”

“…(2023) first synthesized ZnO nps with leaf extract of Cassia Fistula in 1:4 ratio by mixing 0.1Mzinc nitrate hexahydrate, mixture heated for one hour, obtained precipitate dried and muffled. Further doped copper ZnO nps is produced by mixing ZnO nps 0.5g and Copper nitrate salt 0.5g in 100ml distilled water, treated with 0.5M NaOH till precipitate formation, dried in oven at 180℃ for two days, calcinated at 300℃ for 6 hours [3].

Green-Activated Charcoal-Anchored Iron Oxide-Driven Microbial Electro-Fenton System for Sustainable Mitigation of Refractory Contaminants

“…1−3 Industrial effluents include a range of environmental pollutants, with dyes being the most common one due to their uses in textile production, paper manufacturing, cosmetics, plastics, and pharmaceuticals. 4 Coomassie brilliant blue (CBB) is an anionic dye of the triphenyl methane group often used in the textile industry, gel electrophoresis, and many biological applications. 5 Dyes belonging to the triphenyl methane group are notoriously known for their mutagenic and teratogenic activities in living beings.…”

“…Developing regions around the world are increasingly becoming global industrial hubs, largely attributed to the outsourcing of product manufacturing from more developed countries and the presence of a cost-effective labor force. However, ill management of industrial effluents and ineffective regulatory implementation have led to severe contamination of hydric sources, exposing a vast population of these burgeoning regions to a plethora of health hazards. − Industrial effluents include a range of environmental pollutants, with dyes being the most common one due to their uses in textile production, paper manufacturing, cosmetics, plastics, and pharmaceuticals …”

“…These EDCs can mimic the natural hormones in our body, causing hormonal and reproductive disorders. , Hence, it is imperative to effectively manage dye- and micropollutant-laden wastewater to safeguard the anthroposphere. At present, advanced oxidation technologies like sonochemical treatment, photocatalytic degradation, and electrochemical Fenton (EF) systems are employed for treating wastewater with complex and recalcitrant contaminants. ,,, Though effective, these technologies require either external power or additional chemical supplements to carry out the degradation process. This becomes a major hurdle at a larger scale due to the inflated operational expenses, rendering the process economically impractical.…”
