The viability of the Golden Pothos (Epipremnum aureum) plants in different formulations of engineered growth media were evaluated for application in plant-based air filtration systems. To enhance filtration capability, the growth media was engineered to improve toxin capture ability with the aim of maintaining a plant-friendly environment. The growth media used in this study was a hydroponic media composed of activated carbon and porous glass (Growstone). Wet granulation was performed to create a mixed bed of the growth media composed of 40% activated carbon and 60% Growstone. Ionic liquids were tethered to the activated carbon to enhance the toxin capacity and selectivity and then granulated with Growstone to form the enhanced growth media. Two ionic liquids were utilized in this study: 1-butylpyridinium bis(trifluoromethylsulfonyl)imide and choline bis(trifluoromethylsulfonyl)imide, and were selected for their air toxin absorption capacity and reported low toxicity. Eighteen Golden Pothos plants were transplanted to hydroponic and monitored over a period of 40 days in the engineered growth media. Plant metrics were qualitatively and quantitatively analyzed. No statistical difference in normalized growth by % weight gain between the ionic-liquid containing media and the ionic liquid-free growth media was found, however, a statistical difference was observed between the 1-butylpyridinium bis(trifluoromethylsulfonyl)imide and the choline bis(trifluoromethylsulfonyl)imide containing growth medias. The results of this study illustrate that any ionic liquids identified as good candidates based upon their air filtration ability and basic toxicity studies need to be evaluated first for plant viability before studying the efficacy of the full plant-based air filtration system for toxin removal.

金柑子的存活率（绿萝）评估了不同配方的工程生长培养基中的植物在基于植物的空气过滤系统中的应用。为了增强过滤能力，设计了生长培养基以提高毒素捕获能力，目的是维持植物友好的环境。本研究中使用的生长培养基是由活性炭和多孔玻璃（Growstone）组成的水培培养基。进行湿法制粒以产生由40％活性炭和60％生长石组成的生长培养基的混合床。将离子液体束缚在活性炭上，以增强毒素的容量和选择性，然后与Growstone一起制粒，以形成增强的生长培养基。本研究中使用了两种离子液体：1-丁基吡啶双（三氟甲基磺酰基）酰亚胺和胆碱双（三氟甲基磺酰基）酰亚胺，因其对空气中毒素的吸收能力而被选中，且毒性低。将18株Golden Pothos植物移植到水培中，并在经过工程改造的生长培养基中进行40天的监测。工厂指标进行了定性和定量分析。在含离子液体的培养基和无离子液体的生长培养基之间，按重量增加百分比计的归一化生长没有统计学差异，但是，在1-丁基吡啶双（三氟甲基磺酰基）酰亚胺和胆碱双（含三氟甲基磺酰基）的生长培养基。
