Adsorção dos íons de cobre usando pó da palha da carnaúba e bentonita: estudo cinético, termodinâmico e de equilíbrio
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM ENGENHARIA QUÍMICA, 2019-08-23)
The toxicity, non-biodegradability and bioaccumulation presented by industrial effluents
containing heavy metals has become a deep environmental concern. Given this fact, there are already
several treatment techniques ...
Oxidative dehydrogenation of ethylbenzene to styrene over the CoFe2O4-MCM-41 catalyst: Preferential adsorption on the O2-Fe3+O2- sites located at octahedral positions
(2019-01-01)
The present study describes the catalytic performance of cobalt ferrite supported on MCM-41 for the oxidative dehydrogenation of ethylbenzene. The catalytic activity of cobalt ferrite was compared with that of the traditional ...
Zeolitic rock as a new pigment for ceiling paints: Influence of the pigment volume concentration
(Elsevier Science, 2005-09)
The performance of a zeolitic rock, mainly clinoptilolitic (heated at 350 °C) is studied as humidity and ammonia adsorber in ceiling paints. The paints were formulated with 39% and 75% of zeolitic rock by volume of the ...
Remoción de cadmio y plomo de soluciones acuosas mediante semillas de guayaba modificadas con bromuro de hexadeciltrimetilamonio
(Universidad Michoacana de San Nicolás de Hidalgo, 2021-02)
Biosorption is the uptake of metals carried out by a complete biomass, through physicochemical mechanisms such as adsorption or ion exchange. It is a technology that allows to give a treatment and added value to agricultural ...
