Study of Thermally Expanded Graphite for Rehabilitation of Oil-Polluted Water Ecosystems

Abstract

The properties of sorbent on the basis of thermoexplite (STRG) obtained from the engineering center of IngSU "Development of modified sorbation materials" have been investigated. This sorbent is proposed to be used in the elimination of oil spills and products of its processing from the water surface. The porosity of the STGR was analyzed using a mercury porosimeter Pascal 140 and 240 Evo. It is shown that the investigated sample is a volumetric porous tool with a specific pore volume of 35.5 cm3/g. It is found that the available porosity is more than 97.2%. The pore size distribution was studied. Based on the data of the porous system, research on the sorption of oil and oil products by this sorbent. Shown is the high efficiency of STRG in cleaning the water mirror from oil and oil products. The main properties of oil sorbents have been investigated.
