Phytoremediation has been applied as a promising and cost-effective technique for removing nutrient pollutants from wastewater. In this study, the effect of fullerene C60 was assessed on enhancing the phytoremediation efficiency of teak plants over a period of 1 month. Teak plants were supplied with fullerene C60 (0, 25, or 50 mg L) and fed daily with two types of urea plant wastewater (with and without adding optimum ratio of phosphorus and potassium). The required volume of wastewater by the teak plants, nitrogen removal percentage, plant growth parameters (plant height, number of leaves, leaf surface area, and dry biomass), and nutrient content was recorded throughout the study. The results showed that addition of 25 mg L fullerene C60 to urea plant wastewater could increase water uptake and nitrogen recovery of the teak plants. Plant growth and nutrient contents of teak plants were also increased in the presence of 25 mg L fullerene C60. However, addition of 50 mg L fullerene C60 to the wastewater decreased the values for water uptake and nitrogen recovery. The findings indicated that addition of proper amount of fullerene C60 to the teak-based remediation system can increase the efficiency of the plants for nitrogen removal.
植物修复技术已被应用于从废水中去除营养污染物的一种很有前途且具有成本效益的技术。本研究评估了富勒烯 C60 在 1 个月的时间内增强柚木植物的植物修复效率的效果。柚木植物供应富勒烯 C60（0、25 或 50mg/L），每天用两种类型的尿素植物废水（添加和不添加最佳比例的磷和钾）喂养。在整个研究过程中记录了柚木植物所需的废水体积、氮去除百分比、植物生长参数（株高、叶片数、叶片表面积和干生物量）和养分含量。结果表明，向尿素厂废水中添加 25mg/L 的富勒烯 C60 可以增加柚木植物的吸水量和氮回收。在 25mg/L 富勒烯 C60 的存在下，柚木植物的生长和养分含量也有所增加。然而，向废水中添加 50mg/L 的富勒烯 C60 会降低吸水量和氮回收的值。研究结果表明，向基于柚木的修复系统中添加适量的富勒烯 C60 可以提高植物去除氮的效率。
