Decomposition of diclofenac by solar driven photocatalysis at pilot plant scale

Decomposition of diclofenac took around 100 min under all photo-Fenton treatment conditions employed. Decomposition by titanium dioxide photocatalysis took about 200 min. In photo-Fenton treatment, hydrogen peroxide consumption to diclofenac decomposition was about 80-110 mM at pH 2.8 and 40 mM in the other two treatments (neutral pH and pH = 4).
