Photocatalytic Degradation of Reactive Dark Blue with Polyoxometalates

The photocatalytic degradation of the solution of reactive dark blue with undecatungstozirconates with a transition metal Na₅₍₆₎[lXZrW₁₁O₃₉]( X = Cr, Mn, Fe, Co, Ni . Cu , Zn , abbreviated as ZrWX) and bis(undecatungstozirconate) with lanthanide Na₁₃[Ln ( ZrW₁₁O₃₉) 2](Ln = La, Ce, abbreviated as ZrWLn) was studied. The initial pH and the catalyst quantity in the solution have influence on the decolorizing efficiency. The photocatalytic degradation of reactive dark blue solution with ZrWCe was a pseudo-first-order dynamic reaction.
