A continuous flow photoreactor using immobilized nano ZnO semiconductor was studied for degradation of
methylene blue (MB). Response surface methodology was used to optimize the photodegradation percent of
MB using number of UV lamps, slope of the ZnO caoted glass plates, lamp distance and flow rate as influential
variations. The results indicated that the optimum conditions was obtained as follows: slope of 9, three UV
lamps, 14 ml/s flow rate and 10 cm distance of lamp with desirability of 1. The predicted and experimental
values obtained at optimum conditions were 65.05% and 64.66% degradation of M,B respectively.
