摘　　要：研究了海泡石载体对TiO2光催化降解邻苯二甲酸二辛酯(DOP)性能的影响,并考察了DOP降解过程中pH值的变化.结果表明,加入海泡石载体能提高TiO2的光催化效率,附载次数对催化剂性能影响明显,附载5次制成的催化剂效果最佳,并且pH值的变化与DOP降解具有相同趋势,能够反映其降解过程.The effect of sepiolite carrier on the performance of TiO_2 photocatalysed degradation of DOP is studied,and the change of pH value in the process of DOP degradation is researched.The results show that the efficiency of TiO_2 photocatalysed degradation can be improved by adding in sepiolite,and the influence of load times on the photocatalyst performance is obvious.The effect of photocatalyst loaded for 5 times is the best.Besides,the change of pH value and the degradation of DOP have the same trend,which can show its degradation process.
