Evaluating the effectiveness of photocatalysts based on titanium dioxide in the degradation of the dye Ponceau 4R
(2011)
The performance of different titanium dioxide (TiO2) catalysts and a composite based on the association between TiO2 P25 and Zinc Phthalocyanine (TiO2/ZnPc 1.6%) was evaluated in the photocatalytic degradation of the dye ...
Experimental and theoretical insights into the electrooxidation pathway of azo-colorants on glassy carbon electrode
(Elsevier Ltd, 2018)
Sunset yellow, Allura red and Ponceau 4R are azo-colorants with similar chemical structures. These colorants were studied by electrochemical methods at a glassy carbon electrode in phosphate buffer solution (pH 7.0), ...

Enhanced detection of ponceau 4r food dye by glassy carbon electrode modified with reduced graphene oxide
(2018-06-01)
This paper reports the development of a glassy carbon electrode modified with a reduced graphene oxide (r-GO/GCE) for the determination of the food dye named Ponceau 4R (PNC). The modified sensor presented excellent signal ...
Preparação de ferro metálico suportado em polietileno para uso como catalisador flutuante na reação foto-fenton
(Universidade Federal de Santa MariaBrasilEngenharia QuímicaUFSMPrograma de Pós-Graduação em Engenharia QuímicaCentro de Tecnologia, 2019-03-25)
In the present paper, zero-valent iron particles were supported on low density polyethylene. The material produced was used as a buoyant catalyst in the removal of the Ponceau 4R azo dye from an aqueous solution via ...
