Tree bark is promising sorption material for extraction of hydrocarbons from aquatic environments (Review of world and domestic literature)

Abstract

The literature data on the use of bark of coniferous and hardwood trees as a sorption material for the extraction of hydrocarbons from aquatic environments are summarized. It is shown that tree bark is an effective, widespread and cheap sorption material for removing oil and oil products from the water surface. It is also shown that the sorption characteristics of tree bark for oil and products of its processing can be increased by modification with various chemical reagents. It has been revealed that most of the publications are devoted to studies of the bark of coniferous trees as oil sorbents, most of all, the bark of Scotch pine (Pinus sylvestris). It is concluded that the limited number of publications on the use of hardwood bark as oil sorbents makes this line of research promising.
