Abstract The impact of pollutant-based onion-like nanocarbons (ONC) on the growth of common gram (Cicer arietinum) plants is being explored here. ONC were isolated from the pollutant diesel soot, which on oxidative treatment gets converted to water-soluble ONC (wsONC), and were used for the growth of gram plants. It was observed that there was improvement in overall growth of the gram plants having wsONC in comparison with the control set of experiments (without wsONC). The important finding associated with the presented work is that wsONC up to a certain concentration (10 ppm) when supplemented to gram plants imparts an improved growth. Afterward, the growth of the plants was noticed to be decreased, which advocates the dose-dependent properties of wsONC on plant growth. The physical presence of the wsONC nanoparticles inside the roots of treated plants has been examined by scanning electron microscopy.

基于污染物的洋葱状纳米碳用于改善革兰氏植物的生长

摘要 这里正在探索基于污染物的洋葱状纳米碳 (ONC) 对普通革兰 (Cicer arietinum) 植物生长的影响。ONC 从污染物柴油烟尘中分离出来，经过氧化处理转化为水溶性 ONC (wsONC)，并用于革兰氏植物的生长。观察到与对照组实验(没有wsONC)相比，具有wsONC的革兰氏植物的总体生长有改善。与所提出的工作相关的重要发现是，当补充到克植物中时，wsONC 达到一定浓度 (10 ppm) 时会促进生长。之后，注意到植物的生长下降，这表明 wsONC 对植物生长的剂量依赖性。
