Abstract—Technique for production of powder sorbents from renewable plant raw materials, wastes from cereal
plants and sphagnum moss species, were considered. Their sorption properties with respect to dissolved and
emulsiﬁ ed oil products were studied.
It has been shown previously [1–7] that amorphous,
mixed, or crystalline carbon modiﬁ cations produced
in pyrolysis of renewable plant raw materials, wastes
from cultivated plants, are characterized by a high
yield of pure carbon (~99.4–99.8%) and show good
electrochemical, physicochemical, mechanical, and
technological characteristics. This enables use of
carbon modiﬁ cations as anode materials for lithium-
ion (polymeric) batteries and as a starting component
for mechanochemical synthesis in manufacture of high-
melting compounds [6–8].
In addition, renewable plant raw materials can be
used (without a pyrolytic treatment) as effective oil
sorbents in the form of a dispersed powder mass [9–11].
The goal of our study was to produce and examine
powder oil sorbents
from renewable plant raw
materials, wastes from cultivated plants (cereals: wheat
and oat husks) and sphagnum moss species and analyze
their sorption characteristics with respect to dissolved
and emulsiﬁ ed oil products.
As starting raw materials served wastes from cereals
(wheat and oat husks) and sphagnum moss species
collected in raised moors of Lower Amour River region
To reach their air-dry state, the raw materials
were preliminarily dried in a Binder thermal box at
a temperature of 70°C and cleaned by sieving to remove
foreign admixtures. Then the air-dry raw materials were
in turns charged into the working reservoir of a Desi
disintegrator and processed during 7 min for wheat and
oat husks and 5 min for sphagnum moss species until
a homogeneous powder mass with particle size of 45–
50 μm was obtained. The dispersity was monitored with
a Fritsch laser particle size analyzer.
The bulk density was determined by weighing: a 20-
graduated and calibrated polypropylene syringe
was charged with the powders obtained, the surface
was leveled with a plunger, the volume of the powders
was measured, and then they were weighed. After that
a force of 10 kg was applied via a dynamometer to the
plunger handle, with a compacting pressure of 3.2 kg
created, and thus the volume of the powders was
determined and their rammed density was calculated.
The pore capacity was determined against water:
portion of a powder was weighed within
a graduated syringe, water was added, the mixture
was agitated until a ﬂ owing suspension was obtained,
the excess amount of water was squeezed out with the
Three kinds of powder oil sorbents were formed at “Synthesis of
inorganic materials” and “Materials science and technology of
nanomaterials” laboratories at Far-Eastern Federal University.
