Journal ArticleDOI
Effect of Solution pH on the Removal of Paracetamol by Activated Carbon of Dende Coconut Mesocarp
R. C. Ferreira,O. M. Couto Junior,Karina Querne de Carvalho,Pedro Augusto Arroyo,Maria Angélica Simões Dornellas de Barros +4 more
TL;DR: The results indicated that the retention of paracetamol was favored in activated carbon with neutral surface properties, and the adsorption process was non-spontaneous and endothermic with increase in system disorder.
Journal ArticleDOI
Adsorption and desorption of acetylsalicylic acid onto activated carbon of babassu coconut mesocarp
M.I. Hoppen,Karina Querne de Carvalho,R. C. Ferreira,Fernando Hermes Passig,Izadora Consalter Pereira,R.C.P. Rizzo-Domingues,Marcelo Kaminski Lenzi,R.C.R. Bottini +7 more
TL;DR: In this article, the authors evaluated ACB as an environment-friendly material for the adsorption and desorption of acetylsalicylic acid (ASA) from aqueous solution.
Journal Article
Adsorption of Paracetamol Using Activated Carbon of Dende and Babassu Coconut Mesocarp
R. C. Ferreira,H. H. C. De Lima,A. A. Cândido,O. M. Couto Junior,Pedro Augusto Arroyo,K. Q. de Carvalho,Gisele F. Gauze,Maria Angélica Simões Dornellas de Barros +7 more
TL;DR: In this article, the removal of the widely used drug paracetamol from water was investigated using activated carbon originated from dende coconut mesocarp and babassu coconuts.
Journal ArticleDOI
Thermal and thermal-acid treated sewage sludge for the removal of dye reactive Red 120: Characteristics, kinetics, isotherms, thermodynamics and response surface methodology design
Izadora Consalter Pereira,Karina Querne de Carvalho,Fernando Hermes Passig,R. C. Ferreira,R.C.P. Rizzo-Domingues,M.I. Hoppen,G. Macioski,André Nagalli,Felipe Perretto +8 more
TL;DR: In this article, sludge from wastewater treatment plant was used as low-cost adsorbent to remove the dye Reactive Red 120 (RR 120) from an aqueous solution.
Journal ArticleDOI
Multi-component adsorption study by using bone char: modelling and removal mechanisms.
R. C. Ferreira,Diogo Dias,Isabel Fonseca,Maria Bernardo,João Lourenço Castagnari Willimann Pimenta,Nuno Lapa,Maria Angélica Simões Dornellas de Barros +6 more
TL;DR: Modelling results indicated the formation of a first adsorption layer where paracetamol and copper are retained, and a second layer with a great affinity for copper ions after the forming of a Cu-paracetaml complex, leading to higher removal of Cu2+.
