Influence of microwave irradiation on hypochlorite decolorisation of synthetic dyes

Zaštita Materijala, 2016
In this study three synthetic dyes were treated using hypochlorite or combination of hypochlorite and microwave irradiation in order to investigate factors which determine decolorisation of the investigated compounds. An azo dye (C.I. Reactive Orange 16 -

Beyond Removal Efficiency: Environmental Risk Assessment of Tartrazine Degradation via ZnO and TiO2 Nanoparticles in Mussels

Environmental Toxicology, EarlyView.
ABSTRACT Tartrazine (TZ) is a widely used synthetic azo dye with high aqueous stability, resulting in persistence in wastewater. Photoreactive nanomaterials, principally zinc oxide (ZnO) and titanium dioxide (TiO2) nanoparticles (NPs), are frequently employed for dye removal under light‐exposed conditions; nevertheless, their ecotoxicological ...

From Consumer Plastics to Aquatic Toxicants: Oxidative and Endocrine Effects of Microplastics on Fathead Minnow (Pimephales promelas) Larvae

Environmental Toxicology, EarlyView.
ABSTRACT Secondary microplastics (MPs) from single‐use consumer products are rapidly becoming one of the most persistent and widespread pollutants of our time. Freshwater systems act as early sinks for MPs where fragmentation and additive leaching expose aquatic life to a broad spectrum of toxic compounds.

Photocatalytic and Biotechnological Strategies for Remediation of Persistent Organic Pollutants: Mechanisms, Toxicity, and Antimicrobial Perspectives

Environmental Toxicology, EarlyView.
ABSTRACT Persistent organic pollutants (POPs) pose significant ecological and human health risks due to their persistence, bioaccumulation, toxicity, and global distribution. Conventional remediation methods are often inadequate for achieving complete mineralization, demonstrating the need for advanced and substantial approaches.

Contact Allergens Relevant to LGBTQI Populations: A Narrative Review and Practical Considerations

Australasian Journal of Dermatology, EarlyView.
ABSTRACT Allergic contact dermatitis (ACD) is a common inflammatory skin disorder with significant morbidity across populations. Sexual and gender minority (SGM) individuals, including LGBTQI populations, are exposed to unique allergens due to gender‐affirming medical therapies, surgical interventions, cosmetics and grooming practices, sexual health ...

Graphitic Carbon Nitride Catalyzes the Reduction of the Azo Bond by Hydrazine under Visible Light

Nanomaterials
Graphitic carbon nitride is a semiconducting material of a graphite-like 2D layered structure. It is well known for its photocatalytic properties, which can be exploited for solar-light-driven water splitting and degradation of organic pollutants.

Biodegradation of azo dye Remazol Black 5 by Mono Culture Bacteria with Tempe Industrial Wastewater as Co-substrate

International Journal of Technology, 2014
Azo dye is one of the synthetic organic dye groups most widely used in the textile industry. The release of this component into the environment can be harmful to the living organisms and the ecosystems.

The plasticisation model of dye diffusion: Part 6

Coloration Technology, EarlyView.
Abstract Previously published data reported for the temperature dependency of the exhaustion of a mordant dye and acid dye, as well as both the exhaustion and fixation of a reactive dye and adsorption of a direct dye, on three different types of wool substrate, over a diverse range of dyeing temperatures and conditions, were re‐evaluated using the ...

Textile azo dye decolorization and detoxification using bacteria isolated from textile effluents

BioTechnologia, 2019
Azo dyes, which are highly toxic, carcinogenic, and mutagenic for living organisms, are used as coloring chemicals in textile industries. Physicochemical methods used for removing azo dyes are expensive, can generate secondary waste, and are not very ...

Comparative evaluation of reactive dye structures on colour strength enhancement in caustic‐treated regenerated bamboo fabrics

Coloration Technology, EarlyView.
Abstract Regenerated bamboo fibres offer a sustainable alternative to conventional cellulosic materials; however, achieving high and reproducible colour strength with reactive dyes may depend on both fibre accessibility and dye molecular architecture.
