AMMONIUM PHOSPHOMOLYBDATE â MEDIATED PHOTOCATALYTIC
DEGRADATION OF JANUS GREEN B DYE IN AQUEOUS SOLUTION
The ammonium phosphomolybdate–mediated photocatalytic degradation of janus green B was investigated in aqueous solution of dye by monitoring the change in colour. The effect of various parameters such as janus green B concentration, amount of photocatalyst, pH, light intensity, etc. on the rate of photodegradation of janus green B was investigated. The photocatalytic degradation of dye followed pseudo-first order kinetics. Photodegradation was followed spectrophotometrically at λmax = 615 nm. A maximum color removal of 97.9 % was achieved in 4 hours. The mechanism of photocatalysis has been discussed.
