In the current study, composite photocatalyst of Ag3Po4-Ag2CO3 impregnated in alginate beads was synthesized by coprecipitation method and characterized by XRD, FTIR and SEM analyses. Photocatalytic activity of the synthesized impregnated beads was evaluated by degradation of methyl orange (MO) under sun light. The suggested parameters as PH(3-9) and catalyst dosage (0.5-3.5 g/l) were studied using the Response Surface Methodology (RSM) and the optimum conditions were as follows: pH=3and catalyst dosage= 2 g/l. And the methyl orange (MO) removal efficiency reached up to 67.9 % at these optimal conditions. Also kinetic and isotherm of the Photocatalytic degradation were determined in order to more completely understand the degradation mechanism.
