Photocatalytic degradation of alizarin yellow R using TiO2 as catalyst: mechanistic and kinetic investigations
纳米TiO2光催化降解茜素黄R的反应机理与动力学

Alizarin yellow R was photodegraded over nano-TiO2 powder as catalyst and the reaction intermediates were analyzed by GC/MS and LC/MS.Based on the results,three potential photocatalytic degradation pathways were identified for Alizarin yellow R.The hydrolyzed product of Alizarin yellow R,C13H8N3O-5(H) reacted with OH to generate C13H8N3O-6(I) and C13H8N3O-7(J),is sequentially decarboxylated to C12H9N3O4(L) and C12H9N3O5(M).In addition,C13H8N3O-5(H) might be directly decarboxylated to C12H9N3O3(K),sequential...
