Abstract
Photodegradation has good potential for the degradation of organic pollutants such as
dyes. Catalyst used in the degradation is a semiconductor. In this study, the semiconductor
used is PbO, that was synthesize using the precipitation method from precursor Pb(NO3)2
with NaOH precipitator and temperature calcination at 700℃ until 1 hour. The powder
obtained were analyzed using XRD and size of crystallinity of lead oxide (PbO) was
examined with Scherrer equation. From the result of XRD data that were calculated using
Scherrer equation it was obtained crystal size of PbO is 26,52 nm and from the
degradation to methanil yellow was obtained the optimum mass of PbO is 0,008 g,
optimum time is 60 minutes with percentage degradation of 19,89% and 10,78%.
