Studies have shown that biochars, a type of material produced from a carbon-rich organic matter that has undergone pyrolysis, can perform heavy metal sorption from lead-contaminated water. The amount of heavy metal adsorbed is determined by the surface properties of biochars. However, few studies have explored the surface properties quantitively. To address this, samples of biochars originating from two different coffee grounds were charred at 25°C, room temperature, and at charring temperatures of 350°C, 450°C, and 650°C. The biochars were then placed in various concentrations for a time range of 1 hour – 24 hours. The amount of lead adsorbed by the biochars were measured by the ICP-OES. As the charring temperature increases, the amount of lead adsorbed increases. The complete results of this research will be presented.
