2. Maximum colour removal by Fe Na-Y commercial zeolite catalyst is 100% after 4 h
and by Fe Na-Y synthesised zeolite it is 70% after 4 h.
3. Maximum COD removal by Fe Na-Y commercial zeolite catalyst is 67% and by Fe
Na-Y synthesised zeolite it is 46%.

1. Microwave heating of aluminosilicate slurry at the end and at the middle of crys-
tallisation time may be studied.
2. Different exposure times of microwave heating can also be studied.
