摘　　要：以橙黄Ⅱ作为水体污染物,研究了UV/H2O2作用下橙黄Ⅱ光去色和光矿化的效果。结果表明,当橙黄Ⅱ起始浓度一定时,随着H2O2浓度的增大,橙黄Ⅱ光去色和光矿化程度都上升;当H2O2浓度一定时,随着橙黄Ⅱ起始浓度的增大,其光去色和光矿化程度均下降;当pH值从5.9上升到10.0时,橙黄Ⅱ光去色和光矿化程度很接近。With orange Ⅱ as pollutant in water,its photodecolorization and photomineralization by UV/H2O2 were investigated.The result showed that,when orange Ⅱ initial concentration was constant,the photodecolorization and photomineralization extent of orange Ⅱ increased with H2O2 concentration increasing,when H2O2 concentration was constant,the photodecolorization and photomineralization extent of orange Ⅱ decreased with its initial concentration increasing,when the pH value rised from 5.9 to 10.0,the photodecolorization and photomineralization extent of orange Ⅱ changed a little.
