Abstract

Biochar derived from spent coffee grounds was used for the first time as an adsorbent for monitoring and application in a sampling device of gaseous polycyclic aromatic hydrocarbons (PAHs), rather than for the removal of PAHs from the environment, as had been attempted in previous research. The device consists of three parts: an air filtration component, an air sampling component (glass tube filled with lab-made biochar), and a flow controller component. The findings demonstrated that the developed sampling device has a high potential for the collection of gaseous PAHs in ambient air, including naphthalene, acenaphthylene, acenaphthene, fluorene, phenanthrene, anthracene, fluoranthene, and pyrene, under conditions involving low air flow rates (≤ 4 L/min) and low temperatures (≤ 10 °C). Moreover, two connected glass sampling tubes packed with lab-made biochar performed better than a single tube and required less than three hours to prevent significant loss of gaseous PAHs. By using the spiking method on biochar prior to sampling, accuracy levels greater than 80% were achieved for all compounds. Additionally, the efficiency of the biochar was compared with that of a commercial adsorbent (XAD-2), and no significant differences were found. These results suggest that biochar has strong potential for practical applications in the sampling of gaseous PAHs. When comparing production costs, the average price of biochar produced from biomass was estimated to be around 0.18% of the cost of the commercial adsorbent (XAD-2) per sampling.

从废咖啡渣中提取生物炭作为气态多环芳烃的采样装置。
从废咖啡渣中提取的生物炭首次被用作气态多环芳烃(PAHs)取样装置的监测和应用吸附剂,而不是像以前的研究那样试图从环境中去除多环芳烃。该装置由三部分组成:空气过滤组件,空气采样组件(充满实验室制造的生物炭的玻璃管)和流量控制器组件。研究结果表明,在低空气流速(≤4 L/min)和低温(≤10℃)条件下,所开发的采样装置具有很高的收集环境空气中气态多环芳烃的潜力,包括萘、苊、苊、芴、菲、蒽、氟蒽和芘。此外,装有实验室制造的生物炭的两个连接的玻璃采样管比单个管的性能更好,并且需要不到三个小时的时间来防止气态多环芳烃的大量损失。通过在取样前对生物炭使用尖峰法,所有化合物的准确度水平均大于80%。此外,生物炭的效率与商业吸附剂(XAD-2)进行了比较,没有发现显著差异。这些结果表明,生物炭在气态多环芳烃的采样中具有很强的实际应用潜力。当比较生产成本时,从生物质中生产的生物炭的平均价格估计约为每次采样商业吸附剂(XAD-2)成本的0.18%。
