Carbon based foams have recently gained attention in environmental fields and in pollutants adsorption in particular. Therefore, in this work, three carbon-based foams were compared for their ability to act as efficient sorbent of passive samplers for air pollution monitoring. These foams included, silicon carbides (SiC) foams, carbon nanotubes (CNTs) and graphite felts (GFs). The matrices were first subjected to laboratory assessment against polyaromatic hydrocarbons (PAHS), polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs). Results showed that SiC foams generated the highest peak areas among others especially for PAHs analysis. Therefore, matrix effects’ testing was done for GFs and CNTs by comparing the relative peak areas they generate if samples were spiked before or after the extraction. Obtained results showed a high matrix effect for CNT disabling them to desorb the retained PAHs. After this, a sampling campaign was conducted in order to validate the efficiency of GFs and SiC foams in field assessment by comparing them to XAD®-2 resin. Finally, the obtained results validate each other proving the efficiency of both SiC foams and GFs in such assessments. However, the physical properties of SiC foams favour its choice for the synthesis of a novel passive sampler.

碳基泡沫最近已在环境领域，尤其是在污染物吸附方面引起关注。因此，在这项工作中，比较了三种碳基泡沫塑料作为被动采样器进行空气污染监测的有效吸附剂的能力。这些泡沫包括碳化硅（SiC）泡沫，碳纳米管（CNT）和石墨毡（GF）。首先对基质进行聚芳烃（PAHS），多氯联苯（PCB）和有机氯农药（OCP）的实验室评估。结果表明，尤其是对于PAHs分析，SiC泡沫产生了最大的峰面积。因此，通过比较样品在萃取之前或之后加标产生的相对峰面积，对GF和CNT进行了基质效应测试。获得的结果表明，CNT的高基质效应使它们无法解吸保留的PAH。此后，开展了一次采样活动，以通过与XAD®-2树脂进行比较来验证GF和SiC泡沫在现场评估中的效率。最后，获得的结果相互验证，证明了这种评估中SiC泡沫和GF的效率。但是，SiC泡沫的物理特性有利于其选择，用于合成新型无源采样器。
