Preparation of co-doped biochar to improve electron transfer and modulate 1O2 generation: Unraveling the radical-unradical mechanism

Improving the Content of Chemical Elements from the Soil of Waste Heaps Influenced by Forest Vegetation—A Case Study of Moldova Nouă Waste Heaps, South-West Romania

“…It is demonstrated that, on forest plantations on waste dumps, more than 92% of Cu and more than 46% of Pb were removed by black locust [15], even eith Pb being one of the heavy metal pollutants which is difficult to biodegrade [58]. The persistence of Cu in the soil over time is also due to the Cu-O bonds, which are very stable due to the charge distribution around the Cu atoms [59]. In addition to the fact that it is persistent in the soil, copper is itself a rich trace element, having a widespread status and being found in rocks and minerals [60].…”
