Abstract
Textile dyes in the wastewater let-out by industries has been a growing concern for many years. Literature survey reveals that ~15% of dye used in the staining process viz, leather industry, textile processing industry etc., is released in the effluent. Dye pollutants can have drastic effects on the environment. Textile dyes in wastewater are a concern not only because they are displeasing aesthetically but are linked to health hazards as well. It is therefore crucial to investigate techniques to remove these harmful pollutants safely. Treatment of textile dye house effluent by conventional method is an arduous task due to high level of non-degradable chemicals in the dye. Hence advanced oxidation process – photo catalytic reaction using metal oxide is suggested to treat textile dye house effluent. The (Ni2+, Ag2+) co-doped zinc oxide (ZnO) nanocatalyst can be synthesized by chemical co-precipitation method. These co-doped nanoparticles can be used to determine the photo catalytic activity of acid blue 113 dye solution in the presence of sunlight. The degradation of dye solution is monitored by measuring its concentration for the particle size of about 50-100 nm. The Photo catalytic activity is influenced by three important parameters such as initial pH, initial dye concentration and catalyst loading. The effect of these parameters on photo catalytic degradation can be studied and optimized. The photo-catalytic degradation potential of co-doped (Ni2+, Ag2+) ZnO nanoparticles is to be compared with that of un-doped ZnO in acid blue 113 in the presence of sunlight.
