Methylene blue biosorption from aqueous solutions by yellow passion fruit waste.
TLDR
The yellow passion fruit, a powdered solid waste, was tested as biosorbent for the removal of a cationic dye, methylene blue (MB), from aqueous solutions and adsorption of MB was favorable. Expand
A critical review of the estimation of the thermodynamic parameters on adsorption equilibria. Wrong use of equilibrium constant in the Van't Hoof equation for calculation of thermodynamic parameters
Abstract In the adsorption literature, the Van't Hoff equation is used in different manners without any criteria about the concepts of physical-chemistry of equilibrium for calculation ofExpand
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.
TLDR
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.

REMOVAL OF REMAZOL BLACK B TEXTILE DYE FROM AQUEOUS SOLUTION BY ADSORPTION
Abstract Brazilian pine-fruit shells ( Araucaria angustifolia ) in natural form and as activated carbon were tested as adsorbents for the removal of remazol black B (RB) textile dye from aqueousExpand
Yellow passion-fruit shell as biosorbent to remove Cr(III) and Pb(II) from aqueous solution
Abstract In the present study we reported by the first time the feasibility of yellow passion-fruit shell (YPFS- Passiflora edulis Sims. f. flavicarpa Degener) as an alternative biosorbent to removeExpand
Factorial experimental design for biosorption of iron and zinc using Typha domingensis phytomass
Abstract Typha domingensis phytomass was used as a biosorbent for metal ions removal from wastewater. A full 23 factorial design of experiments was used to obtain the best conditions of biosorptionExpand
Adsorption of Reactive Red M-2BE dye from water solutions by multi-walled carbon nanotubes and activated carbon.
TLDR
The Avrami fractional-order kinetic model provided the best fit to the experimental data compared with pseudo-first-order or pseudo-second-orders kinetic adsorption models and the equilibrium data were best fitted to the Liu isotherm model. Expand
Application of cupuassu shell as biosorbent for the removal of textile dyes from aqueous solution.
TLDR
The cupuassu shell (Theobroma grandiflorum) which is a food residue was used in its natural form as biosorbent for the removal of Reactive Red 194 and C.I. Direct Blue 53 dyes from aqueous solutions and the Avrami fractionary-order kinetic model provided the best fit to experimental data. Expand
Pecan nutshell as biosorbent to remove Cu(II), Mn(II) and Pb(II) from aqueous solutions.
TLDR
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. Expand
Application of Brazilian pine-fruit shell as a biosorbent to removal of reactive red 194 textile dye from aqueous solution kinetics and equilibrium study.
TLDR
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). Expand
