Polyaniline (pANI) was pyrolyzed under a nitrogen atmosphere to get porous pANI-derived carbons (PDCs). To increase the porosity of the carbons further, the PDCs were activated at 600-800 °C in the presence of KOH. The obtained PDCs were firstly applied in liquid-phase adsorptions in order to remove hazardous organics from both water and fuel effectively via adsorption. PDC-700, activated at 700 °C, showed record high adsorption capacities from water for the removal of hazardous organics such as diethyl phthalate and Janus Green B, as representative organics for industrial chemicals (endocrine disturbing agent) and organic dyes, respectively. Moreover, PDC-700 had record high adsorption capacity for the removal of 4,6-dimethyldibenzothiophene from a model fuel. The plausible mechanisms were also suggested to explain the remarkable adsorptions both from water and fuel. The adsorbents could be regenerated in a facile way and reused in adsorption up to several cycles. Therefore, the PDCs could be suggested as a new class of adsorbents for the purification of both water contaminated with organics and fuel having a high concentration of thiophenics.

在氮气氛下将聚苯胺（pANI）热解，得到多孔的pANI衍生碳（PDC）。为了进一步增加碳的孔隙率，在KOH的存在下于600-800°C活化了PDC。首先将获得的PDC用于液相吸附，以通过吸附有效地从水和燃料中去除有害有机物。在700°C下活化的PDC-700对水中有害的有机物（如邻苯二甲酸二乙酯和Janus Green B）的去除表现出了很高的吸附能力，分别用作工业化学品（内分泌干扰剂）和有机染料的代表有机物。此外，PDC-700具有从模型燃料中去除4,6-二甲基二苯并噻吩的高吸附能力。还提出了可能的机理来解释水和燃料的显着吸附。吸附剂可以方便的方式进行再生，并可以重复进行多达几个循环的吸附。因此，PDCs可能被建议作为一种新型的吸附剂，用于净化被有机物污染的水和具有高噻吩浓度的燃料。
