Abstract
Currently, industrial wastes are typically combusted at incineration plants, and the resulting ashes are sent to landfill. This practice raises issues, such as potential toxicity of the leachate to the environment, as well as the loss of valuable metals left in the waste. Therefore, from both economic and environmental standpoints, it is becoming increasingly important to recover valuable metals from industrial waste. In this work, a transformative recovery of vanadium (conversion nearly 100%) from leaching solutions of carbon black waste (metal leaching efficiency > 97%) which originates from oil refineries in Singapore, has been systematically studied. Interestingly, three distinctive alkaline earth vanadate nanomaterials were successfully synthesized from the leaching solutions by a facile hydrothermal process, that is, single-crystal calcium vanadate nanorods (Ca10V6O25) oriented along the [001] direction, strontium vanadate nanorods with ellipsoid-like assembly (Sr10V6O25), and barium vanadate polyhe...
