DEGRADASI RHODAMIN B SECARA FOTOKATALISIS DAN OZONOLISIS DENGAN PENAMBAHAN TIO2-NIFE2O4, TiO2-CuFe2O4, DAN TiO2-MnFe2O4
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.
