Macadamia shells were used to prepare modified carbon by chemical agent H2O2 (25%) in 48 hours with coke ratio: H2O2 = 1:10. Modified carbon from Macadamia shells with chemical agent H2O2 has capable of adsorption heavy metal copper (Cu 2+ ) at an assumption concentration is 30ppm in the optimum conditions such as pH = 4, dose is g/l, and the processing time is 30 minutes. The result showed that the adsorption ability of the material reached the highest efficiency is . This result showed that modified carbon from shells Macadamia by chemical agent H2O2 capable of removing applications on heavy metal copper (Cu2+) in wastewater. |
