Approaches for peat modification to improve oil sorption capacity

摘要

Oil pollution is one of the major environmental problems. The aim of this study is to investigate the possibilities to use peat and its modification products for oil sorption. Peat is a prospective material for oil sorption because it has such advantages as low cost, biodegradability and relatively high parameters of specific surface area and porosity. We have studied the sorption characteristics of high-moor peat with different botanical compositions and levels of decomposition, as well as the effect of thermal treatment on the oil sorption capacity, buoyancy and water sorption capacity of peat in comparison with the effect achieved by means of other methods of peat modification: silylation, methylation and treatment with organosilicon compounds. We have determined the optimal conditions for thermal modification of peat to have an effect on hydrocarbon sorption characteristics.
