Removal of lead (Pb2+) from aqueous medium by using chars from co-pyrolysis

- Chars from the pyrolysis of mixtures composed by pine, plastics, and scrap tires.
- Removal of Pb2+ from aqueous medium using chars.
- Char from mixture of the three raw materials with worst Pb2+ removal performance.
- Char from mixture composed by tires and plastics more efficient in Pb2+ adsorption.
- Chemisorption with Ca2+, K+, and Zn2+ exchange on Pb2+ removal by tire derived char.
