ABSTRACT
Degradation of Rhodamin B has been done by photocatalytic and ozonolysis using TiO2-
Anatase and TiO2-NiFe2O4, TiO2-CuFe2O4, TiO2-MnFe2O4 catalysts, photocatalytic method
used lamp with λ = 365 nm and ozonolysis methode used ozon reactor. Analysis of degradation
result used spectrofotometer UV-Vis. TiO2-NiFe2O4, TiO2-CuFe2O4, TiO2-MnFe2O4 catalyst
were characterized by XRD to determine size and structure of crystal. The solution of
Rhodamin-B 2 mg/L was degraded 93,33 % without catalyst after being photolysed for 180
minutes and after adding 0,02 g TiO2-MnFe2O4, TiO2-CuFe2O4, TiO2-Anatase, TiO2-NiFe2O4
catalyst. The additional consentration in a row are 99,55 %; 99,77 %; 100 %; 100 %. The
solution of Rhodamin B 2 mg/L was degraded 99,33% without catalyst after being ozonolysis
for 25 minutes and after adding 0,02 g of TiO2- MnFe2O4, TiO2-CuFe2O4, TiO2-Anatase, TiO2-
NiFe2O4 catalysts with the additional consentration in a row are 99,77 %, 99,77 %, 99,77 %,
100 %. So the degradation of Rhodamin B using ozonolysis method was faster than
photocatalytic with catalysts and without catalyst.
Keywords: Rhodamin B, Photocatalytic, Ozonolysis, TiO2-Anatase, TiO2-NiFe2O4, TiO2-
CuFe2O4,TiO2-MnFe2O4.
