Photocatalytic Degradation of Indigo Carmine Dye Using Calcium Oxide

Table 2

The effect of irradiation of different light sources on the percentage of degradation of indigo carmine dye solution using calcium oxide.

Photocatalyst	Light source	Contact time (min); (pH of dye solution is 9-10)	Percentage of degradation (dye at pH 9-10)	Contact time (min); (pH of dye solution is 12)	Percentage of degradation of dye (pH 9-10)
0.12 g calcium oxide	Visible	70	95.4	150	100
	Long UV	60	98.4	100	100
	Short UV	30	98.48	90	100
