Cu/N/Pd /Ni nanocomposites from wastes Printed circuit boards (PCBs) to remove endocring disruptors

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.
