Huge amounts of anthropogenic environmental pollutants appearing in nature mean an emerging problem. Oil shale is a convenient candidate, wherewith these contaminations can be removed from our natural environment, taking into account its sorption ability and low price. However, oil shale has a crumbling nature, which restricts its facile usage. Hence, oil shale was transformed into more handleable forms, using binding materials. Two oil shale composite forms were prepared by applying sodium alginate and agar. A cationic and an anionic chemicals, benzyltriethylammonium chloride and sodium 2,3-diisopropylnaphthalene-1-sulfonate, respectively, were used as model pollutants, and their sorptions on these newly prepared composites were studied. Sorption properties of oil shale powder and oil shale composites were compared. In the composite materials, oil shale properly sorbed the model pollutants (the binding material did not cover the sorption sites); furthermore, oil shale composites had significantly higher removal efficiency compared to that of the oil shale powder: 208 ± 15.6 (oil shale–agar) and 171 ± 22.8 (oil shale–alginate) vs 140 ± 11.1 µmol/g for the cationic compound; 151 ± 1.6 (oil shale–agar) and 165 ± 7.6 (oil shale–alginate) vs 81.5 ± 2.6 µmol/g for the anionic compound. Results of diffusion models for the two composites show that the opposite charges of the solutes largely influence the rate of their diffusion, owing to the interaction between the solute and the composite material. These results indicate that oil shale and its composites are applicable candidates as sorbents, from which the most effective one can be chosen by considering the chemical properties of the actual pollutant to be removed.

自然界中出现的大量人为环境污染物意味着一个新出现的问题。油页岩是一种方便的选择，考虑到其吸附能力和低廉的价格，可以从我们的自然环境中清除这些污染物。但是，油页岩具有易碎的性质，这限制了其的易用性。因此，使用粘结材料将油页岩转化为更易处理的形式。通过施加藻酸钠和琼脂制备两种油页岩复合形式。分别使用阳离子和阴离子化学品苄基三乙基氯化铵和2,3-二异丙基萘-1-磺酸钠作为模型污染物，并研究了它们在这些新制备的复合材料上的吸附性能。比较了油页岩粉和油页岩复合材料的吸附性能。在复合材料中 油页岩正确吸附了模型污染物（结合材料未覆盖吸附部位）；此外，与油页岩粉相比，油页岩复合物的去除效率明显更高：208±15.6（油页岩-琼脂）和171±22.8（油页岩-藻酸盐），而阳离子化合物的去除效率为140±11.1 µmol / g。151±1.6（油页岩-琼脂）和165±7.6（油页岩-藻酸盐），而阴离子化合物为81.5±2.6 µmol / g。两种复合材料的扩散模型结果表明，由于溶质与复合材料之间的相互作用，溶质的相反电荷在很大程度上影响其扩散速率。这些结果表明，油页岩及其复合材料可用作吸附剂，
