Abstract
Abstract
Synthesize ZnO-Activated Carbon (ZnO-AC) use the time, concentration, pH degradation Acid Orange 7 dyes. The stages preparation of synthesize included sample preparation, making shell activated carbon candlenut, ZnO-KA characterization and degradation study.. SEM-EDX analysis results showed an uneven morphology with a percentage of ZnO mass of 58.46%. ZnO-KA degrade Acid Orange 7 for 8 hours with a concentration of 50 ppm and at pH alkali obtained percentage degrade of 96.23%.
Key words: Degradation, Acid Orange 7, ZnO-KA
Keywords: fotodegradasi, Acid Orange 7, ZnO-Karbon Aktif (ZnO-KA)
