In this study, we synthesized and employed the amine impregnated activated carbon as an efficacious adsorbent for uptaking gasoline vapor. For this regard, anthracite as activated carbon source and hexamethylenetetramine (HMTA) as amine were selected and utilized. Physiochemical characterization of made sorbents were evaluated and investigated using SEM, FESEM, BET, FTIR, XRD, zeta potential, and elemental analysis. The synthesized sorbents provided an excellent textural features as compared with the literature and other activated carbon based sorbents and impregnated with amine. Our findings also suggested that in addition to high surface area (up to 2150 m² / g), the micro- meso pores created (Vmeso / V micro = 0.79 Cm ³ / g) surface chemistry may significantly affect the gasoline sorption capacity, which here the role of mesoporous is further highlighted. V meso for amine impregnated sample and free activated carbon was 0.89 and 0.31 Cm ³ / g, respectively. According to the results, the prepared sorbents have a potential capability in uptaking gasoline vapor and with line this, we report a high sorption capacity of 572.56 mg / g. After, four cycles used the sorbent had a high durability and about 99.11% of the initial uptake was maintained. Taking together the synthesized adsorbents as an activated carbon provided an excellent and unique features and enhanced gasoline uptake, therefore its applicability in uptaking gasoline vapor can be substantially considered.

在这项研究中，我们合成并使用胺浸渍活性炭作为吸收汽油蒸气的有效吸附剂。为此，选择和使用无烟煤作为活性炭源和六亚甲基四胺（HMTA）作为胺。使用 SEM、FESEM、BET、FTIR、XRD、zeta 电位和元素分析评估和研究制成的吸附剂的理化特性。与文献和其他基于活性炭的吸附剂和浸渍胺相比，合成的吸附剂提供了优异的结构特征。我们的研究结果还表明，除了高表面积（高达 2150 m ² / g）外，还产生了微孔（Vmeso / V micro = 0.79 Cm ³/g) 表面化学可能显着影响汽油吸附能力，这在这里介孔的作用进一步凸显。胺浸渍样品和游离活性炭的 V meso 分别为 0.89 和 0.31 Cm ³ / g。根据结果​​，制备的吸附剂具有吸收汽油蒸汽的潜在能力，据此，我们报告了 572.56 mg / g 的高吸附容量。之后，使用四个循环后，吸附剂具有高耐久性，并保持了约 99.11% 的初始吸收。将合成的吸附剂作为活性炭结合在一起，提供了卓越而独特的特性并增强了汽油吸收，因此可以充分考虑其在吸收汽油蒸汽方面的适用性。
