Description
Summary:This study utilized agricultural waste, namely corn leaves, as biochar. The resulting biochar complies with SNI No 06-3730-1995 for water and ash. SEM-EDS characterization showed that biochar from corn leaves could be used as an adsorbent for BOD and COD in hospital wastewater. Activation of the biochar was carried out with an activator agent, namely ZnCl 2 . SEM-EDS determined the pore and elements analysis. Activated Biochar Corn Leaves (ABCL) consist of 50.35 mg/L of the carbon produced with a carbonization temperature of 300°C. Three grams of ABCL reduced COD up to 34.62 mg/L in 4.5 hours and a maximum of 41mg/L of BOD in 4.5 hours. While in three hours, a maximum of 2.5 gr ABCL decreased BOD 35.44%, and COD 30 mg/L.
