摘　　要：以TiO_2半导体为光催化剂对溶液中的分散染料的降解进行了研究。在通空气的条件下,光照50分钟可便50mg/L的染料溶液完全脱色,COD_(Cr)去除率可达70％以上。研究中探讨了通空气、溶液的pH值、光距、TiO_2重复使用等因素对光催化降解的影响。Photodegradation of disperse dyes solution using semiconductor TiO2 as catalyst has been studied. Under blowing air condition, after 50 min irradiation, it was found that disperse dyes solution of 50 mg/l has been completely decoloured, and the removal rate of COD was over 70%. Effects of air, pH, lamp distance and reuse of TiO2 on degradation were also discussed.
