[en] The experiment for degradation of organic compound that was contained at liquid radioactive waste has been done. This experiment was purposed for conditioning liquid radioactive waste so it will be easy for manage and save for disposal. Thin layer of photocatalist TiO2 that was immobilized at glass matrix is one of alternative for degradation of organic compound. The thin layer of TiO2 was prepared by calcination process of Ti(IV) bis ethylasetatodiisopropoxide 0.5M at 400 oC. This thin layer was characterized by spectrophotometer, SEM and XRD. The result of characterization was proven that photocatalist have anatase crystal structure because it has band gap energy around 3.11 eV to 3.27 eV and has XRD pattern it with anatase structure. The capability of photocatalist for degradation of organic compound was 185.7 mg/KWh or the quantum yield value was 1.25 X 10-4. This capability show that thin layer photocatalist TiO2 that immobilized at glass matrix can be used for conditioning liquid radioactive waste. (author)
