Abstract

This study focuses on the development and optimization of a water removal device for biogenic volatile organic compounds (BVOCs) from plant emissions. BVOCs play a crucial role in various ecological processes and have potential therapeutic effects on human health. However, it is challenging to accurately detect and analyze BVOCs due to their very low concentrations and interference by water vapor. This study systematically evaluates different filler materials and ratios to alleviate water vapor interference while maintaining BVOCs' integrity. The experimental results demonstrate that the combination of MgSO₄ + Na₂SO₄ mixed filling and CuSO₄ layered filling in a 3:3:1 ratio can effectively improve the collection efficiency and detection accuracy of BVOCs. Meanwhile, the effectiveness of the device in improving the detection of volatile compounds in plant samples is also confirmed by the VOC verification experiments on Michelia maudiae and Cinnamomum camphora tree species after mechanical damage. The experimental results show that the device is effective in improving the detection of volatile compounds in plant samples. The findings provide a powerful technical means for exploring the role of BVOCs in environmental monitoring and scientific research.

基于优化填充率的工厂挥发性有机化合物脱水装置的设计与性能研究

本研究的重点是开发和优化从工厂排放物中去除生物挥发性有机化合物（BVOCs）的水去除装置。BVOCs 在各种生态过程中发挥着至关重要的作用，并对人类健康具有潜在的治疗效果。然而，由于 BVOCs 的浓度非常低，且受到水蒸气的干扰，因此准确检测和分析 BVOCs 具有挑战性。本研究系统地评估了不同的填充材料和比例，以减轻水蒸气的干扰，同时保持 BVOCs 的完整性。实验结果表明，将 MgSO4 + Na2SO4 混合填充和 CuSO4 分层填充按 3:3:1 的比例组合使用，可有效提高 BVOCs 的收集效率和检测精度。同时，该装置在提高植物样品中挥发性化合物检测效率方面的效果也通过对机械损伤后的Michelia maudiae和Cinnamomumum camphora树种进行VOC验证实验得到了证实。实验结果表明，该装置能有效提高植物样本中挥发性化合物的检测能力。这些发现为探索 BVOCs 在环境监测和科学研究中的作用提供了有力的技术手段。
