The potential of Iris pseudacorus and Typha domingensis to remove the pharmaceutical active compound (PhAC) Furosemide from a nutrient solution was assessed. Both plants were exposed to 2 mg L⁻¹ of furosemide during 21 days and the removal of furosemide was monitored. Vessels without furosemide were also implemented as control systems for plants development. Likewise, unplanted vessels with furosemide were employed to assess abiotic removal mechanisms. All vessels were covered with aluminum foil to avoid photodegradation of the compound. Both plants showed potential to remove Furosemide, attaining, at the end of the experiment, a removal of 42.0–66.9% and 40.5–57.8%, for Typha and Iris, respectively. The plants do not presented a visible negative stress response to the exposure to furosemide, having a positive growth rate at the end of the experiment. Biodegradation seems to play an important role in furosemide removal, being enhanced by the presence of the plants. The two macrophytes presented different removal behaviors, particularly in the first 48 h of contact time. FUR removal by Iris follows a pseudo-first order while by Typha is divide in different phases. These results indicate that different plants species seem to have different mechanisms to remove pollutants from water.

• Highlights

• PhACs removal potential of Iris pseudacorus and Typha domingensis was assessed.

• Plants were exposed to 2 mg L⁻¹ of furosemide during 21 days.

• Both macrophytes showed good removal efficiencies.

• Biodegradation of furosemide seems to be the main removal mechanism.

• Plants demonstrated different removal behavior along the experiment.

• Removal mechanisms of plants seem to differ between species.

评估了鸢尾鸢尾和香蒲（Typha domingensis）从营养液中去除药物活性化合物（PhAC）速尿的潜力。将两种植物在21天内暴露于2mg L ^-1的速尿中，并监测速尿的去除。没有速尿的容器也被用作植物开发的控制系统。同样，未植入速尿的血管被用于评估非生物去除机制。所有容器均覆盖有铝箔，以避免化合物发生光降解。两种植物均具有去除速尿的潜力，在实验结束时，香蒲和鸢尾的去除率分别为42.0–66.9％和40.5–57.8％。分别。在暴露于速尿时，植物没有表现出明显的负胁迫响应，在实验结束时具有正的生长速率。生物降解似乎在速尿的去除中起着重要作用，由于植物的存在而增强了。两种大型植物表现出不同的去除行为，尤其是在接触的前48小时内。艾里斯（Iris）去除FUR遵循伪一阶，而香蒲（Typha）去除FUR在不同阶段。这些结果表明，不同的植物物种似乎具有从水中去除污染物的不同机制。
