文摘

Pb₃O₄ could react with organic dyes in aqueous solution under visible light irradiation, in which Pb₃O₄ was transformed into Pb₃(CO₃)₂(OH)₂ along with oxidation of the organic dyes. Cu²⁺ has considerable effect on the reaction. In the presence of Cu²⁺, MO (20 ppm) and RhB (10^鈥? mol L^鈥?) were completely degraded under visible light within 6 and 20 min, respectively, while both Pb₃O₄ and Cu²⁺ keep almost stable during photodegradation. The mechanisms of the reactions with and without Cu²⁺ ions were studied. The photochemical system of Pb₃O₄ cooperating with Cu²⁺ ions is probably used for the treatment of organic pollutants in water under visible light.
