Excited states quenching of phenosafranine dye by electron donors
(Elsevier Science Sa, 2005-03)
The quenching of the excited singlet and triplet states of phenosafranine by aromatic amines, methoxybenzenes and triethanolamine was investigated in acetonitrile and methanol. The rate constants for the aromatic quenchers ...
Optimization and mechanisms for biodecoloration of a mixture of dyes by Trichosporon akiyoshidainum HP 2023
(Taylor & Francis Ltd, 2017-09)
Trichosporon akiyoshidainum HP2023 is a basidiomycetous yeast isolated from Las Yungas rainforest (Tucumán, Argentina) and selected based on its outstanding textile-dye-decolorizing ability. In this work, the decolorization ...
Quantum efficiency of the photo-induced electronic transfer in dye-TiO2 complexes
(Royal Society of Chemistry, 2018-10)
We present a method based on a time-dependent self-consistent density functional tight-binding (TD-DFTB) approach, able to predict the quantum efficiency of the photoinjection process in a dye-TiO2 complex from a fully ...
The utilization of leaf-based adsorbents for dyes removal: A review
(Elsevier Science, 2019-01)
The presence of organic dyes in the aquatic environment is a serious global problem because of the serious negative consequences on the quality of ecosystems. Among various physico-chemical methods, the adsorption could ...
High-pressure phase behaviour of the system (CO2 + C.I. Disperse Orange 30 dye)
(Academic Press Ltd - Elsevier Science Ltd, 2012-05-08)
The dyeing of textile fibres of poly-ethylene terephthalate (PET) in a supercritical medium is an environmentally friendly technological alternative to the conventional water-based dyeing process. In this work, the solubility ...
Reactive RED 195 dye removal using chitosan coacervated particles as bio-sorbent: Analysis of kinetics, equilibrium and adsorption mechanisms
(Elsevier, 2018-10)
Chitosan particles (CP) prepared by coacervation technique were used as bio-sorbent material to remove the azo RR-195 dye; removal percentage (%RM) and adsorption capacity (Q) in batch adsorption experiments under different ...
Challenges of dye removal treatments based on IONzymes: Beyond heterogeneous Fenton
(Elsevier, 2021-06)
Dyes are recalcitrant organic compounds that generate environmental damage. Heterogeneous Fenton-like catalysts, catalytic systems using reusable solid-state catalysts as an alternative for Fe2+ in solution, have gained ...
A comparative study on the photophysics and photochemistry of xanthene dyes in the presence of polyamidoamine (PAMAM) dendrimers
(Wiley VCH Verlag, 2018-04-17)
The photophysical and photochemical properties of the xanthene dyes Eosin Y, Erythrosin B, and Rose Bengal are evaluated in the presence of amino-terminated polyamidoamine (PAMAM) dendrimers of relatively high generation ...
Sorption behavior of polyvinyl alcohol/bentonite hydrogels for dyes removal
(Springer, 2019-06)
Hydrogels seem as possible materials to solve the dyes contamination in water. In this study, polyvinyl alcohol (PVA) based nanocomposite hydrogels having 3 wt.% bentonite were prepared by an innocuous physical crosslinking ...
