Spent Coffee Ground (SCG) Biochar for Select Heavy Metal Removal

摘要

1.Our patent pending process can result in an acidic to neutral biochar, unlike other products on the market. 2.The processing temperature of biochar has significant impacts on biochar's properties 3.Our biochars have the potential to remove select heavy metals 4.Freundlich absoiption fits better for Cu, Zn, Ni, slightly better for Pb. 5.On-going: more characterization and analysis of biochar needed. Further study to better understand the control parameters for sorption.
