DIAZ-DIAZ, Miguel Ángel; RIVAS-TRASANCOS, Lester; LEON-BARRIOS, Maydeibys  e  ACOSTA-SANCHEZ, Jessell. Absorbent material to pick up oil spills in water and soils. Rev Cub Quim [online]. 2018, vol.30, n.2, pp.289-298. ISSN 2224-5421.

The aim of this study was the pilot scale production of an absorbent material base bagasse to pick up oil spills in water and soils. For this purpose, it was prepared 30 kg of dry basis absorbent material by chemical treatment of the bagasse, which was previously dried for 72 h at room temperature, submitted to treatment with sodium hydroxide and hydrogen peroxide. The product was packed in nylon mesh bags, each one containing 10 kg of wet absorbent pads. Dynamic conditions test of the absorbent material obtained is conducted in a moving aqueous phase (hydrophilic conditions) containing hydrocarbons (oleophilic conditions), according to method ASTM F 726-12. The average sorption capacity obtained for the modified bagasse material by chemical treatment is considered acceptable, compared to some of the known commercial products.
