Comparison between two forms of granular activated carbon for the removal of pharmaceuticals from different waters
(2016-06-02)
The aim of this study was to evaluate the performance of two forms of basic granular activated carbon (GAC), mineral (pH = 10.5) and vegetal (pH = 9), for the removal of three pharmaceuticals, as sulphamethoxazole (SMX), ...
Granular Activated Carbon Treatment May Result in Higher Predicted Genotoxicity in the Presence of Bromide
(2016-07-28)
Certain unregulated disinfection byproducts (DBPs) are more of a health concern than regulated DBPs. Brominated species are typically more cytotoxic and genotoxic than their chlorinated analogs. The impact of granular ...

Synthesis of PtSn nanoparticles on carbon materials by different preparation methods for selective catalytic hydrogenation of citral
(Taylor & Francis, 2019-07)
In this work, PtSn bimetallic catalysts supported on three different carbons were prepared by two methods: a) conventional impregnation followed by a reduction treatment under H2-flow (CI) and b) deposition-reduction in ...
Avaliação da remoção de compostos farmacológicos em filtros de carvão granular biologicamente ativado em escala de laboratório
(Universidade Estadual Paulista (Unesp), 2010-09-24)
A contaminação por compostos farmacêuticos nos ambientes aquáticos e sua difícil remoção no tratamento convencional de água representam um desafio às companhias de saneamento. O uso de carvão ativado granular (CAG) em ...
