DEGRADASI SENYAWA PARAQUAT DALAM PESTISIDA GRAMOXONE® SECARA FOTOLISIS DENGAN PENAMBAHAN TiO2-ANATASE
ABSTRACT: This research is
conducted to know whether the photolysis method by adding TiO2-anatase can degrade
the paraquat compound in Gramoxone pesticide. Photolysis method is conducted by
using UV 10 watt lamp at the wavelength of 365 nm. The result shows that
photolysis method could degrade the paraquat compound at 4.0 mg/L concentration
as 16.02% after 60 minutes irradiation. Paraquat compound with the similar
concentration by adding 10 mg unmixed TiO2-anatase coulddegrade 26.01% after 60
minutes irradiation and 62.30% by mixing TiO2-anatase. Furthermore, paraquat
with the same concentration and TiO2-anatase addition could degrade 99.54%
after 240 minutes irradiation.
