Penguraian Pentaklorofenol (PCP) secara Fotokatalitik Menggunakan TiO2 Imobil
ABSTRACT: Imobilization of
titanium plate using titanium diisopropoxide as a precursor, that will be used
as a catalyst for degradation of pentachlorophenol (PCP) has been done. In this
study 10 ppm of pentachlorophenol (PCP) solution at pH 5 was used as a model of
organic polutant. Irradiation was done with and without TiO2 as a catalyst.
Sampling was done at interval time
of 15, 30, 45, 60, 75, 90, 105,
120, 135, 150, 165, 180, 195, 210, 225 and 240 minutes. Parameter examined
after irradiation were the changes of spectrum and pH, the formation of
chloride ions and intermediate compounds. The decreased of pH and PCP
concentration and the formation of chloride ions and intermediate compounds
showed that PCP has already degraded.
