Desain Fototransfomator Plat Tembaga (Ii) Oksida Cuo Pada Asam Humat

This study was conducted using a phototransformator reactor which was used to
degrade humic acid with calcined photocatalyst of CuO plate for 1 hour at 4000C. This
reactor was designed in hexagonal form made of glass with a thickness of 3 mm, in this
reactor filled with 200 mL of humic acid with the help of sunlight. The phototransfomator
process is carried out through a process of degradation of humic acid using a reactor which is
performed at 1, 2, 3, 4, 5 hours. Absorption of visible light humic acid before and after
degradation is 265 nm. The results show that in the outer light the highest value occurs at 2
hours which is 49.70%
