DEGRADASI SENYAWA IMIDAKLOPRID SECARA ADVANCED OXIDATION PROCESSES DENGAN PENAMBAHAN TIO2-ANATASE
ABSTRACT: Imidacloprid is
active compounds in Confidor 200 SL with have toxical character. Degradationof
Imidacloprid in Advanced Oxidation Processes (AOPs) method by using TiO2
catalyst canreduce toxic level. Advanced Oxidation Processes (AOPs) method
which is used is Sonolysis,Photolysis, and Ozonolisis. The result of sonolysis,
Photolysis, and Ozonolysis measured byspectrophotometer UV-Vis with λ 400-600
nm, and than optimum degradation waste afteraddition of catalys measured by
HPLC. The result of degradation of Imidacloprid 6 mg/L using sonolysis without
addition catalys is more smallest from addition catalys which degradated in 60
minute, temperature 25±1 °C. At the same time with Photolysis methode for
addition catalys we get the degradation is more biggest from addition catalys.
Degradation percentage of imidacloprid without addition of TiO2-anatase reach
is small from with addition of TiO2.Measure using HPLC for each methode we get
more than one peak in chromatogram. It meansthere are other coumpounds in
imidacloprid solution.
