Article history: Received 30 August 2017 Accepted 18 September 2017 Available online 02 October 2017 The textile industry is a field which has strong environmental impacts due its high consumption of water and emission of pollutants, specially the dyes. The dyes are organic or synthetic substances which alter the physicochemical characteristics of the water body in which they are released, incr...

Laccases are green biocatalysts that possess attractive advantages for the treatment of resistant environmental pollutants and dye effluents. A putative laccase-like gene, laclK, encoding a protein of 29.3 kDa and belonging to the Cu-oxidase_4 superfamily, was cloned and overexpressed in Escherichia coli. The purified recombinant protein LaclK (LaclK) was able to oxidize typical laccase substra...

In this work, an efficient photocatalyst based on gamma-cyclodextrin-modified titanium dioxide nanoparticles (TiO2/γ-CD NPs) was synthesized and used for photocatalytic degradation of rhodamine B (RhB), methyl orange (MO) and methylene blue (MB). The results of FESEM, EDX, TEM, FT-IR, XRD and BET surface area measurement showed that the TiO2 NPs were effectively modifi...

4,4-Difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) dyes have received an upsurge of interest because they possess a variety of distinctive and desirable properties such as high absorption coefficients, narrow absorption and emission bands, good stability, excellent emission quantum yields, and have promising applications in supramolecular fluorescent gels, solar cells, sensing and imaging. A s...

The past three decades have witnessed extensive research in developing a range of non-metallic fused heterocyclic organic dyes for dye sensitized solar cells (DSSCs).

A novel strategy for the stitching of a tripodal ligand into a bi-metallic two-dimensional (2D) coordination polymer has been reported. The reaction of 5-nitrosalicylaldehyde based ligand H3L with nickel acetate resulted in the metal functionalized 2D extended network via potassium induced activation of the nitro group of the ligand. The compound is highly active towards photo-degradation of or...

This manuscript describes a synthesis of nanocrystalline TiOF2 film. The nanocrystalline TiOF2 becomes chemically attached to the surface of the glass slide. These films are robust and can be recycled as photocatalysts for the degradation of organic dyes and solvents. These films also have significant antibacterial properties upon irradiation.

The preparation and the photophysical behaviour of novel julolidine derivatives designed for displaying excited state intramolecular proton transfer (ESIPT) are reported. These dyes exhibit panchromatic photoluminescence covering the whole visible spectral range, both in organic solvents and in the solid state.

Textile industries are one of the largest consumers of water and hence producers of liquid effluents. The dyeing and finishing processes generate volumes of wastewaters in the range 45450 m3 per ton of product [1], containing salts, acids, bases, additives and unfixed dyes. A suitable treatment of these complex wastewaters should lead to a strong decline on the organic load, and desirably to a ...

Water pollution caused by industrial organic compounds is a serious global environmental problem. In some developing countries, the wastewater discharged from the textile industry is estimated to be more than one billion tons annually. The dyes in the discharge usually contain functional groups that could lead to high toxicity, i.e. the aromatic amine groups. Some dyes are resistant to light, h...
