SINTESIS TIO2/ZEOLIT SEBAGAI FOTOKATALIS PADA PENGOLAHAN LIMBAH CAIR INDUSTRI TAPIOKA SECARA ADSORPSI-FOTODEGRADASI
ABSTRACT: Research on
synthesis of TiO2 /Zeolite and Its application as photocatalyst in Tapioca Starch
Wastewater Treatment has been investigated. Research conducted by
synthesis of TiO2 /zeolite by ion
exchange process to exchangeable cations in natural zeolite by Ti4+ solution at
varied concentration of 0,12 M, 0, 24 M and 0,48 M followed by oxidation and calcination
process, followed characterization by analysis of Ti content, XRD measurement, specific
surface area measurement and
photoactivity toward methylene blue photodegradation. TiO2 /zeolite photoactivity toward
photodegradation of tapioca starch wastewater was tested by exposing
photocatalyst-wastewater suspension with UV light in varied time and ratio of
photocatalyst weight: volume of wastewater.
Result of research showed that TiO2 /zeolite has a photoactivity to decrease COD and
cyanide content of tapioca starch wastewater. The photoactivity related to
specific surface area and photoactivity toward methylene blue photodegradation
physical character and also photodegradation time. The highest photoactivity
reached by TiO2 /zeolite-1 which is resulted by Ti4+concentration of 0,12 M in
the ion exchange process to natural zeolite.
