Herein, for the first time it has been demonstrated that hydrazine (Hz) could significantly promote the bisphenol A (BPA) degradation in the Fenton reaction catalysed by Fe[Co(CN)(6)]center dot 2H(2)O Prussian blue analogue (Fe-III-Co PBA). Results indicate that the dramatic enhancement of BPA degradation could be partly attributed to the induced homogeneous Fenton reaction by the enhanced dissolution of Fe-III-Co PBA. Meanwhile, the Hz coordinated iron site (H2NH2N-Fe), which is evolved from the original water coordinated iron site (H2O-Fe), was identified as the main active site. A possible reaction pathway involving the proposed active iron species was proposed. (C) 2016 Elsevier B.V. All rights reserved.
