摘 要:
以天然浮石为载体,用溶胶-凝胶法制备含pb2＋的TiO2光催化剂,并用制备的光催化剂处理活性艳红X-3B染料废水.研究了催化剂制备时溶胶的涂覆次数、掺杂Pb2＋浓度、染液pH值、处理温度对染料废水处理效果的影响.结果表明,当涂覆4次、Pb（NO3）2浓度为2.0g/L,处理温度70℃条件下处理75min,脱色率可达89%.[著者文摘]

Abstract:
TiO2- loaded natural pumice photocatalyst and doped of lead ion （Pb^2＋/TiO2/Pumice） was prepared by sol- gel technique using natural pumice as the supporter. The photocatalytic degradation of reactive brilliant red X- 3B solution was performed in aqueous suspensions of pb^2＋/TiO2/Pumice. The treatment effect of catalyst was examined on times of sol overlaying, concentration of doping of Pb^2＋ in preparation of catalyst, different pH and temperature of dyeing water. The result indicate that the colour removal can reach 89%, when pumice was overlayed four times, concentration of lead nitrate was 2.0 g/L and the temperature was 70℃.[著者文摘]
