Biochar (BC) produced from agricultural crop residues has
proven effective in sorbing organic contaminants.
This study
evaluated the ability of dairy-manure derived biochar to sorb
heavy metal Pb and organic contaminant atrazine.
Two biochar
samples were prepared by heating dairy manure at low
temperature of 200 °C (BC200) and 350 °C (BC350).
The untreated
manure (BC25) and a commercial activated C (AC) were
included as controls.
Sorption of Pb by biochar followed a
