ABSTRACT

 

The photocatalytic degradation of rhodamine B was studied using ZnO as semiconductor in the presence of sunlight. Zinc oxide appears to be a suitable alternative for water treatment. A comparison of quality parameters of canal water, polluted water (dye containing) and treated water has been done. Parameters like pH, BOD, COD, DO, conductivity, TDS, alkalinity, hardness, calcium, magnesium, chloride, fluoride, sulfate and nitrate were determined. After photocatalytic treatment, the results showed complete colour removal, approx 50% COD reduction, 26% nitrate reduction, pH, hardness, magnesium reduction along with enhancement in conductivity and in the biodegradability of the polluted water (dye containing) from 2.33 to 2.6 which shows the mineralization of the water
