In this work, nanofibrous membranes made of keratin extracted
from wool were prepared by electrospinning process and char-acterized in their morphology, diameter distribution, thickness,
porosity and specific surface area.
Afterwards, the prepared membranes were tested as adsorbents
for Methylene Blue from aqueous solution through preliminary
adsorption tests carried out in batch.
In particular, the adsorption capacity and the removal efficiency
of keratin nanofibrous membranes were evaluated in function of
initial dye concentration, pH, adsorbent dosage, time and temper-ature.
Moreover, equilibrium (Langmuir, Freundlich, Dubinin–
Radushkevich and Temkin) and kinetic (pseudo-first order,
pseudo-second order) models were used to fit experimental data
and the isosteric heat of adsorption was calculated
