| description | To increase photocatalitic activity of TiO2, the preparation and
characterization of TiO2 photocatalyst on resin accompanied with photoactivity
test for Cu(II) ion photoreduction, have been carried out. The dispersion of TiO2
on resin was carried out by mixing TiO2 that had been suspensed in ethanol
(TiO2(et)) with resin, then continued with the ethanol evaporation at temperature
60-70 oC. The characterizations were carried out by using X-Ray diffraction
(XRD), FTIR and Diffuse Reflactance UV (DR-UV) methods. Photoreduction
process was executed in batch system, by irradiating mixture of Cu(II) solution
and TiO2(et)/resin photocatalyst. The influences of photocatalyst mass, Cu(II) ion
concentration, andirradiating time towards photoreduction result were also
evaluated. The research results showed that TiO2(et)/resin dried at 60-70 oC does
not destroy resin and TiO2 structure. Result of activity examination showed that
TiO2(et)/resin photocatalyst has highest activity (94.52%) on Cu(II) ion
photoreduction followed by TiO2/resin (91.44%) and TiO2 (67.58%). The increase
of photocatalyst mass (5-50 mg), could improve the effectivness of the
photoreduction, but further increase of mass (50-100 mg) could reduce it. A low
Cu(II) concentration (10 mg/L) yielded effective photoreduction (93.44%), but for
higher concentration (15-100 mg/L) decreased photoreduction effectivity (89.24-
86.41%). The irradiating time of 1-24 hours increased effectivness of Cu(II) ion
photoreduction, but for longer irradiating than 24 hours, photoreduction
effectivity was decreased. |
