Photocatalytic degradation of safranine O in the presence of nickel oxide

Abstract

Now a days, nature is suffering from a serious problem of environmental pollution. Industrial effluents are major sources causing water pollution. In the last two decades photocatalysis has been attracted the attention of scientific community all over the world. The present work is, on the photocatalytic behaviour of nickel oxide on safranine O. The progress of the reaction has been monitored spectrophotometrically. The influence of pH, amount of semiconductor, dye concentration and light intensity were thoroughly investigated and well regulated. The photodegradation reactions were conducted in basic medium and over the room temperature. The present study suggests that semiconductor might have played an important role in the degradation of dyes through their photocatalytic reactions. The tentative mechanism of photocatalytic reaction has been discussed.
