Journal ArticleDOI
Applications of Brazilian pine-fruit shell in natural and carbonized forms as adsorbents to removal of methylene blue from aqueous solutions - kinetic and equilibrium study.
Betina Royer,Natali F. Cardoso,Eder C. Lima,Julio C.P. Vaghetti,Nathalia M. Simon,Tatiana Calvete,Renato Cataluña Veses +6 more
TL;DR: The Brazilian pine-fruit shell (PW) is a food residue, which was used in natural and carbonized forms, as low-cost adsorbents for the removal of methylene blue from aqueous solutions, and it was observed that C-PW leaded to a remarkable increase in the specific surface area, average porous volume, and average porous diameter of the adsorbent when compared to PW.
Journal ArticleDOI
Pecan nutshell as biosorbent to remove Cu(II), Mn(II) and Pb(II) from aqueous solutions

TL;DR: The feasibility of pecan nutshell (PNS, Carya illinoensis) as an alternative biosorbent to remove Cu(II), Mn(II) and Pb( II) metallic ions from aqueous solutions is reported for the first time.
Journal ArticleDOI
Application of Brazilian pine-fruit shell as a biosorbent to removal of reactive red 194 textile dye from aqueous solution kinetics and equilibrium study.
Eder C. Lima,Betina Royer,Julio C.P. Vaghetti,Nathalia M. Simon,Bruna Müller da Cunha,Flávio A. Pavan,Edilson Valmir Benvenutti,Renato Cataluña-Veses,Claudio Airoldi +8 more
TL;DR: It was observed that the treatment of the Brazilian pine-fruit shell with chromium leaded to a remarkable increase in the specific surface area and average porous volume of these biosorbents when compared to unmodified Brazilian pine -fruit shell (PW).
Journal ArticleDOI
Application of carbon adsorbents prepared from Brazilian-pine fruit shell for the removal of reactive orange 16 from aqueous solution: Kinetic, equilibrium, and thermodynamic studies
Tatiana Calvete,Eder C. Lima,Natali F. Cardoso,Julio C.P. Vaghetti,Silvio L.P. Dias,Flávio A. Pavan +5 more
TL;DR: Equilibrium data were better fit to the Sips isotherm model using C-PW and AC-W as adsorbents and the fractionary-order kinetic model provided the best fit to experimental data compared with other models.
Journal ArticleDOI
Comparison of Jatropha curcas shells in natural form and treated by non-thermal plasma as biosorbents for removal of Reactive Red 120 textile dye from aqueous solution

TL;DR: In this article, the effects of pH, shaking time and temperature on adsorption capacity of Reactive Red 120 (RR-120) dye from its aqueous solutions were studied.
