Study
of the effectiveness of using industrial porous polymer films, foams and fiber
materials as sorbents for petroleum products
Abstract
Abstract.A comparative analysis of the structure and
sorption properties of nano- and microporous materials based on large-capacity
industrial polymers in the form of films, fibers, nonwoven and foam materials,
including those manufactured as packaging materials, geotextiles, and medical
devices, was carried out. It has been shown that the sorption capacity,
sorption kinetics and buoyancy of the studied materials are determined by the
geometric size and shape of the sorbent, the size and volume of the pores. The
most effective were foam materials (polyurethane foam, polyethylene foam),
which retain buoyancy at high sorption capacity (17–39 g/g). The possibility of
using porous polymer materials as carriers of bacteria-biodegraders of oil and
oil products has been demonstrated.
Key words: petroleum
product sorbents, industrial polymer films, fibers, foamed polymer materials,
spunbond, biodegraders
