Water remediation from hydrocarbons is crucial to reduce health risks. Numerous costly and, sometimes, sophisticated methods were proposed over the years. Herein, an innovative green procedure for porous polyanilines preparation is reported. Polyaniline (PANI) was synthesized by three different approaches ranging from traditional to more eco-friendly ones. Thermal, optical and morphological features of the resulting materials were investigated along with their surface properties. Finally, PANIs were tested as sorbents for hydrocarbons removal from waterbodies. Although an overall fast and high sorption efficiency is always observed, the effective hydrocarbons abatement performed by 'green' PANIs is particularly welcome in the context of environmental protection. Moreover, the sorption efficiency retention after five-run recycling tests suggests potential applications in wastewater remediation.
从碳氢化合物中进行水修复对于降低健康风险至关重要。多年来，人们提出了许多成本高昂且有时很复杂的方法。在此，报道了一种用于制备多孔聚苯胺的创新绿色方法。聚苯胺（PANI）通过从传统方法到更环保方法的三种不同途径合成。研究了所得材料的热、光学和形态特征以及它们的表面性质。最后，测试了聚苯胺作为从水体中去除碳氢化合物的吸附剂。尽管总体上总是观察到快速且高效的吸附效率，但在环境保护背景下，“绿色”聚苯胺所实现的有效碳氢化合物减排尤其值得欢迎。此外，经过五次循环测试后吸附效率的保持表明其在废水修复方面具有潜在应用。
