On the catalytic hydrogenation of polycyclic aromatic hydrocarbons into less toxic compounds by a facile recoverable catalyst
(ELSEVIER SCIENCE BV, 2009)
Here we present the catalytic hydrogenation of polycyclic aromatic hydrocarbons (PAHs) to less toxic mixtures of saturated and partial unsaturated polycyclic hydrocarbons under mild reaction conditions using a magnetically ...
Desenvolvimento de um flotador por ar dissolvido em coluna de estágios para tratamento de águas oleosas.
(Universidade Católica de Pernambuco, 2018-02-27)
A dissolved air flotation column - FAD, commonly uses principles of operation based on the operation of a gas-liquid fluidized bed. In the present research, a column scale FAD column was developed, consisting of stages, ...
Electrochemical removal of nitrite using an activated copper rotating cylinder electrode
(Electrochemical Society, 2017-08)
An undivided electrochemical reactor with a rotating cylinder electrode was examined for the removal of nitrite from a synthetic effluent, 30 mmol dm−3 NaNO2 in 0.1 mol dm−3 Na2SO4 as supporting electrolyte. Nitrite was ...
Use of Cassava Wastewater Treated Anaerobically with Alkaline Agents as Fertilizer for Maize (Zea mays L.)
(Inst Tecnologia Parana, 2010-01-01)
The wastewater of the processing of cassava's flour (manipueira) was submitted to the anaerobic treatment in two phases: acidogenic and methanogenic. In the acidogenic phase, the wastewater was stabilized with NaOH (ASH) ...
