The performances of an innovative material based on graphene multilayers in a 3D structure similar to expanded graphite, Grafysorber G+ (Directa Plus), have been tested via in field applications on a real contaminated site. Several experimental tests were performed using Grafysorber inside adsorbent devices (booms and pillows) to treat waters polluted by oil. The experimental campaign was carried out with the aim of comparing the performances of Grafysorber with those of polypropylene (PP), which is the material used worldwide in case of water oil spill clean-up activities. The results achieved have confirmed a considerably higher selective adsorption capacity of Grafysorber compared to PP, and configure the new material as a promising alternative to standard materials in enhancing oil spill remediation by selective adsorption.
一种基于多层石墨烯的创新材料Grafysorber G+（Directa Plus），其结构类似于膨胀石墨，呈三维结构。该材料已在一个实际污染场地进行了现场应用测试。使用Grafysorber在吸附装置（围油栏和吸油枕）中对受油污染的水进行了多项实验测试。开展该实验的目的是将Grafysorber的性能与聚丙烯（PP）的性能进行比较，聚丙烯是全球在水油泄漏清理活动中使用的材料。所取得的结果证实，与PP相比，Grafysorber具有更高的选择性吸附能力，并且将这种新材料配置为通过选择性吸附提高溢油修复效果的标准材料的一种有前景的替代品。
