NOVELTY - Degrading organic dye waste-water involves mixing 0.9 milliliter of oxone solution having molar concentration of 0.01 moles/litre with 0.005 gram of magnetic nano catalyst cobalt-iron doped prussian blue-based coordination polymer-graphene oxide nano-catalyst at room temperature under natural sun light irradiation. The 50 mL of rhodamine B dye wastewater with a mass concentration of 25 milligram/litre is added with stirring for 30 minutes. The degradation efficiency of rhodamine B is 100%. USE - Method for degrading organic dye waste-water (claimed). DETAILED DESCRIPTION - Degrading organic dye waste-water involves mixing 0.9 milliliter of oxone solution having molar concentration of 0.01 moles/litre with 0.005 gram of magnetic nano catalyst cobalt-iron doped prussian blue-based coordination polymer-graphene oxide nano-catalyst at room temperature under natural sun light irradiation. The 50 mL of rhodamine B dye wastewater with a mass concentration of 25 milligram/litre is added with stirring for 30 minutes. The degradation efficiency of rhodamine B is 100%. The magnetic nanocatalyst cobalt-iron doped prussian blue-based coordination polymer-graphene oxide is separated and recycled.
