Application of sorbents obtained from plant waste for absorption of petroleum products

Sorbents were obtained from plant waste (straw and leaf litter) by activating with solutions of sodium hydroxide and sodium carbonate, as well as heat-treating them in an argon atmosphere. On the example of diesel fuel, the oil capacity of the obtained materials is determined. It was established that the heat treatment of the source and activated materials leads to an increase in the values of oil intensity. It was shown that the sample obtained by activating straw with the solution of Na2CO3 and subsequent heat treatment in an argon atmosphere has the greatest oil capacity. This sample is comparable in oil intensity with known industrial sorption materials.
