摘要：Cerium-iron oxide, as a mixed form or as a multi ferrite composite can be a potent material to remove organic and inorganic contaminants through affinity based binding. Being semi conducting in nature they also exhibit elevated photo-catalysis at nanoscale. This effect of photo catalysis can be utilized for degradation of dyes. The cerium-iron core-shell nanostructures were formed by simple co-precipitation technique and analyzed for stability over a period of one week. The stable suspensions were subjected to particle size analysis and zeta potential measurement. Polystyrene is a rigid polymer which can be used to fabricate a simple matrix over with a layer of cerium-iron oxide composite can be coated. This matrix will be used as a column in a simulated reactor which can effectively permeate water and remove the organic and inorganic contaminants in a normal atmospheric and environmental condition. Having high affinity for the heavy metals like cadmium and arsenic iron nanoparticles serve as the chemical affinity provider and cerium acts as a photocatalyst. The waste water can be analyzed by UV Visible spectroscopy for the amount of contaminants present before and after the treatment process to measure the distribution of the heavy metals in the samples.
