【摘要】 以半导体氧化物（ZnO／TiO2）为催化剂，利用太阳光光源对电镀含铬（Ⅵ）废液加以处理，经90min太阳光照（1182．5W／m2），铬（Ⅵ）含量由初始17．2mg／L降至0．05mg／L．去除率达99％以上．处理后的电镀废液中铬（Ⅵ）含量远远低于国家工业废水排放标准．更多还原

【Abstract】 Study on semiconductor catalysis for photo reduction of Cr(Ⅵ ). Using sunlight as photo energy to treat Cr(Ⅵ) in plate waste-water ZnO/TiO2 showed a good effect. After the photo-catalyst being added, and then treated with sunlight for 90 min, the concentration of Cr(Ⅵ ) was reduced from 17. 20 mg/L to 0. 05 mg/L. The clearance reached to about 99%.更多还原
