Adsorptive removal of Cr(vi) from wastewater by α-FeOOH hierarchical structure: kinetics, equilibrium and thermodynamics
A novel hollow urchin-like α-FeOOH hierarchical structure was fabricated via a one-pot hydrothermal procedure without using any templates, surfactants or organic raw materials. An inside-out amorphous ripening mechanism was proposed to unravel its structural evolution. The kinetics, equilibrium and...

| description | A novel hollow urchin-like α-FeOOH hierarchical structure was fabricated
via
a one-pot hydrothermal procedure without using any templates, surfactants or organic raw materials. An inside-out amorphous ripening mechanism was proposed to unravel its structural evolution. The kinetics, equilibrium and thermodynamics of its adsorptive removal of Cr(
vi
) from wastewater were comprehensively investigated. It was found that the adsorption process can be depicted using a pseudo-second-order model, and a high adsorption capacity of 58.97 mg g
−1
was obtained from the equilibrium adsorption isotherm. Also, the thermodynamic parameters (
i.e.
, enthalpy, entropy and Gibbs free energy) at different temperatures were acquired to reveal a spontaneous adsorption process, with both physical and chemical characteristics.
The Cr(
vi
) adsorptive performances (including adsorption kinetics, equilibrium isotherms and thermodynamics) of hollow urchin-like α-FeOOH hierarchical structure were comprehensively studied. |
