AB  - Mushrooms are widely investigated and recognized as perspective materials for the removal
of various pollutants from wastewater effluents. In this study, mosaic puffball Handkea
utriformis was tested as a new biodegradable, but relatively stable material for Cd2+
adsorption from aqueous mediums. The fruiting body of Handkea utriformis goes through the
process of autodigestion, during which their inside – gleba is turned into a powdery, sporebearing
mass, and the lower portion of the fruiting body – subgleba, into a dark, dry, spongy
mass. The impurities and spores present on the surface of the subgleba can be removed in a
simple process of purification with acidic and alkaline solutions. The purification decreases
the hydrophobicity of the surface of this material, and therefore increases the number of
surface functionalities, knowing that subgleba consists of sugars, proteins and polymeric
pigments (melanins). The subgleba purified with 0.1M HCl and 0.1M NaOH (Sp) was used
for the removal of Cd2+ from the aqueous solution. The efficiency of the material for
adsorption of Cd2+ was investigated in a batch system under the constant initial concentration
of adsorbate and pH and different concentrations of the adsorbent. Composition and surface
morphology were characterized by using FT-IR spectroscopy, SEM and EDX analysis.
Concentrations of Cd2+, before and after adsorption, were determined by using Atomic
Absorption Spectroscopy (AAS). The Langmuir and Freundlich isotherm models, as well as
kinetic models, were evaluated to correlate experimental data. The results showed that kinetic
data were well fitted by a pseudo-second-order model. Isotherms studies revealed that the
best fit was achieved with the Langmuir isotherm model with a maximum adsorption capacity
of 15.2, 19.1 and 25.0 mg g-1 at 25, 35 and 45ºC, respectively.
