Abstract

In this study, Batch Test was carried out on the adsorption abilities to heavy metal of FWC, which occurred during the carbonization process was part of recycling methods of food waste. The heavy metals used in the experiment were lead and cadmium; mixing its solution with carbonized ratio of 50:1, respectively. The different concentrations were applied with 50, 100, 200, 400, and $800\;{\mu}g/m{\ell}$. When, the initial concentration is less than 200mg/l, there has been a high removal ratio of 20% to 50%. Comparing the test results on Lanmmuir and Freundlich adsorption isotherms, the Freundilich adsorption isotherm was well compatible.
