Synthesis of PbTiO3 as a photocatalyst for degradation of sodium dodecyl sulfate (SDS) and sodium dodecylbenzene sulfonate (SDBS) has been carried out. Catalyst PbTiO3 has been synthesized by hydrothermal method at temperature 220 °C for 30 min. Synthesis of PbTiO3 was prepared with composition variation of TiO2:PbO (w/w) at (1:3), (1:2), (1:1), (2:1), (3:1), and pH at 3, 5, 7, 9, 11. The PbTiO3 was characterized by XRD, FTIR, DR-UV, and SEM-EDX. Photodegradation performance was analyzed with visible light sources for 30 min and calculated using Spectrophotometer Uv–Vis. PbTiO3 at ratio TiO2:PbO 1:2 (w/w) has the maximum degradation percentage of SDS (70.42%) and SDBS (84.84%). The optimum pH to perform photodegradation was pH = 5 with degradation efficiency of SDS and SDBS were 85.69% and 85.56%.
