Bisphenol A degradation using waste antivirus copper film with enhanced sono-Fenton-like catalytic oxidation.

This study investigated the applicability of waste antivirus copper film (CF) as a Fenton-like catalyst. The reaction activity of HO and CF in combination was significantly enhanced by ultrasound (US) irradiation, and the synergy factor calculated from bisphenol A (BPA) degradation using CF-HO-US was 9.64 compare to that of dual factors.

Application of the anion-exchange resin as a complementary technique to remove residual cyanide complexes in industrial plating wastewater after conventional treatment.

Cyanide is highly toxic and must be destroyed or removed before discharge into the environment. This study examined the ability of commercial anion-exchange resins to remove residual cyanide complexes from industrial plating wastewater as a complement to conventional treatment. Cyanide removal experiments were conducted with various initial concentrations, reaction times, and temperatures, and the presence of co-existing anions.
