Abstract:
Dibutyl phthalate and nonylphenol from endocring disruptors were removed photocatalycally with nanocomposites derivated from printed circuit board wastes. These wastes represent 3% of the total mass of waste electric and electronic equipment and have revealed the following composition: 5.52 wt% C, 2.18 wt% H, 0.73 wt% N, and 7.86 wt% Br . The physicochemical properties of the nanocomposite was investigated with XRD, Raman and FTIR analysis. For maximum Dibutyl phthalate and nonylphenol yields (99% and 98%) of the optimal photocatalytic time, nanocomposite concentration and Dibutyl phthalate and nonylphenol concentrations were 12 min., 1,2 mg/l and 800 mg/l and 920 mg/l, respectively.
