Abstract:
Industrial activity has been generating wastewater and need to be treated. Biochar is a potential and low-cost adsorbent as an alternative solution for removal metals ion. Fe and Mn are metals ion that produced in mining industrial activities. In this study, biochar has derived from coconut shell and wood. Biochars were produced in modified rector for 4 hours. The sorption abilities of biochars were measured in fixed column at laboratory in room temperature. Biochar derived from coconut shell has high sorption ability for removal metals ion than wood. Isotherm models of metals ion sorption fitting in Freundlich model. Isotherm model of metals ion sorption were evaluated with ARE and chi-square. Thus, biochars are potential carbon material to solve the wastewater problems.
