This study throws light on utilization of visible light in removal dyes from wastewater using commercial PbCrO 4 /TiO 2 (P-25) composite which was prepared by grinding TiO 2 (P-25) with PbCrO 4 to decrease the adhesion properties of PbCrO 4 . As-prepared catalyst was characterized by DRS, XRD and N 2 adsorption-desorption. The morphology was examined by SEM. The photodegradation of rhodamine B (Rh B) product in the presence of PbCrO 4 / TiO 2 (P-25) composite was dependent on the pH of the medium. In 2 \ pH \ 10, Rh B was involved in photodegradation via N-deethylation terminated at rhodamine 110 while at pH = 2 rhodamine 110 underwent chromophore destruction. Obtained data showed that HO 2• /O 2•-species were involved in degradation of dye. Commercial PbCrO 4 /TiO 2 (P-25) composite is considered as good visible light-sensitive photocatalyst for removing Rh B.
