Various eco-friendly and cost-effective hydrocarbons clean-up methods based on natural sorbents were developed and tested, in order to prevent the massive environmental damage due to the petroleum spills. Among these sorbents, natural zeolitic tuffs are easily available and have numerous adsorptive properties that make them appropriate for the removal of petroleum substances. This study aims to preliminary investigate the sorption capacity of natural zeolites from a deposit located at Racos, Brasov County, Romania for diesel oil sorption. Two different zeolitic materials having particles size <10 microns and 1-3 mm, thermally activated at two different temperatures, were used in this study. Zeolite samples were characterized in terms of major elements and major oxides contents, using inductively coupled plasma optical emission spectrometry (ICP-OES), after acid digestion and also in terms of Cation Exchange Capacity (CEC). For the experiments, an amount of 3.5 g of each adsorbing materials was placed in crystallizing glass columns dish, then diesel oil was added until the saturation of the whole bed. Afterwards, the excess of diesel oil was removed using a filter paper. The sorption capacity (SC) was determined by weighing. The results showed SC ranging between 0.19 ? 0.26 g/g, for zeolites with particles size of 1-3 mm and, much higher SC, in the range of 1.5 ? 1.6 g/g, for zeolites with particles size < 10 microns. This study offers valuable information for the use of Romanian natural zeolites in the clean-up of different media contaminated with petroleum hydrocarbons.
