This report examines the adsorption capacity of sewage sludge based hydrochar for lead. A sewage sludge-based adsorbent for lead removal targets two major environmental issues, organic waste disposal and lead pollution. The methods for the experiments outlined in this report were based on previous work completed by Hunter Wieckowski. Hunters work examined the adsorption capacity of sewage sludge based Hydrochar for copper. The adsorption data for lead was fit to two major adsorption models: Langmuir and Freundlich. Both empirical models had similar goodness of fits, with the Freundlich model fitting the data slightly better than Langmuir. Comparing the adsorption data for lead and copper showed that the adsorption of lead was higher than copper at equilibrium concentrations less than 0.2 mg/g and less than copper at equilibrium concentrations greater than 0.2 mg/g. The max adsorption capacity of sewage sludge hydrochar for lead was found to be 9.19 mg/g and was compared to the max adsorption capacity for other hydrochar materials.
