Cyanine dyes in solid state organic heterojunction solar cells
(2014-01-01)
Today numerous cyanine dyes that are soluble in organic solvents are available, driven by more than a century of research and development of the photographic industry. Several properties specific to cyanine dyes suggest ...
Removal of dyes by lignocellulose adsorbents originating from biodiesel production
(2014)
In this study, use was made of tucumã cake, in natura (TCN) and thermally treated (TCT), as potential alternative adsorbents for the adsorption of cationic and anionic dyes. The effects of the parameters: contact time, ...
The mechanism of dephosphorylation of bis(2,4-dinitrophenyl) phosphate in mixed micelles of cationic surfactants and lauryl hydroxamic acid
(2009-11-06)
(Figure Presented) Mixed micelles of cetyltrimethylammonium bromide (CTABr) or dodecyltrimethylammonium bromide (DTABr) and the α-nucleophile, lauryl hydroxamic acid (LHA) accelerate dephosphorylation of bis(2,4-dinitrophenyl) ...

Uptake of acid black 210 dye by organo montmorillonite clay minerals
(European Journal of Chemistry, 2013-12)
Two clays rich in montmorillonite were modified and used as adsorbents. The clay minerals were modified with hexadecylpyridinium cation (HDP+) in order to obtain organomontmorillonites,which were used for retaining acid ...
Derivatizações aniônica e catiônica de resíduos do processamento dos fios de algodão para remoção de corantes têxteis
(Universidade Tecnológica Federal do ParanáCuritibaPrograma de Pós-Graduação em Ciência e Tecnologia Ambiental, 2014-02-17)
The Brazilian textile industry occupies an important role in the economy and ranks among the 10 largest world producers The effluents generated in the process of fabrics dyeing contain 15 to 50% of dyes and others contaminants. ...
Fenton-like degradation of methylene blue using Mg/Fe and MnMg/Fe layered double hydroxides as reusable catalysts
(2020-03-15)
In this work, the Layered Double Hydroxide (LDH) containing magnesium (Mg) and iron (Fe) was modified with Mn to investigate the effect of the addition from the structural and catalytic point of view. These materials were ...
Dye aggregation and influence of pre-micelles on heterogeneous catalysis: a photophysical approach
(Elsevier BVAmsterdam, 2011-12)
Common cationic dyes used for laser and fluorescent probes present low solubility in water. In order to increase the dye concentration in aqueous solutions, anionic surfactant can be added. The strong interaction between ...
