摘　　要：以Pb(NO_(3))_(2)、NaOH和NH_(4)Cl粉末为原料,采用简单的机械研磨法制备了Pb(OH)Cl样品。针对3种有机染料(亚甲基蓝(MB)、甲基橙(MO)和罗丹明B(Rhodamine B,RhB)),研究了在可见光照射下添加和不添加H_(2)O_(2)时Pb(OH)Cl样品的光催化降解性能。结果表明:经时间为1 h的机械研磨,Pb(NO_(3))_(2)、NaOH和NH_(4)Cl 3种粉末能发生固相反应,生成平均粒径约为0.8μm的Pb(OH)Cl粉体;Pb(OH)Cl样品对有机染料表现出的降解能力较弱;在H_(2)O_(2)辅助下,Pb(OH)Cl样品能在60~75 min的时间内完全降解MB、MO和RhB等污染物,H_(2)O_(2)明显改善了Pb(OH)Cl的光催化性能。Pb(OH)Cl is prepared from Pb(NO_(3))_(2),NaOH,and NH_(4)Cl powders through a simple solid-reaction method.In this article,the photocatalytic-degradation properties of the obtained Pb(OH)Cl sample for different organic dyes(methylene blue(MB),methyl orange(MO),and rhodamine B(RhB))through H_(2)O_(2)addition are investigated under visible-light irradiation.Results showed that Pb(OH)Cl particles with an average size of 0.8μm were obtained by the solid reaction within 1 h.Pb(OH)Cl showed suitable degradation ability for MO but almost none for MB and RhB.H_(2)O_(2)effectively improved the photocatalytic properties of Pb(OH)Cl and almost completely degraded MO,MB,and RhB within 60~75 min.
