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

Highlights: [•] 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. [ABSTRACT FROM AUTHOR]
