摘　　要：以N掺杂TiO2试剂为催化剂,降解偶氮直接耐酸大红4BS溶液,同时外加4种浓度不同的阴离子溶液,探讨了HCO3-,F-,NO3-,H2PO4-等阴离子对N/TiO2化学试剂催化活性的影响。实验表明,HCO3-,F-,NO3-,H2PO4-等阴离子对N/TiO2化学试剂的催化活性有显著影响。因此,可以通过外加不同的离子来提高或降低N/TiO2的活性。The liquor of 4BS is degraded using the N/TiO2 as catalyst. The effects of HCO3^-, F^-, NO3^-, and H2PO4^- on the catalytic activity of N/TiO2 are studied. The experiments indicated that inorganic anions used in the experiments have notability effect on the catalytic activity of N/TiO2. The catalytic activity of N/TiO2 could be enhanced or reduced by adding different kinds of inorganic anions.
