Description
The structure of the supramolecular coordination polymer SCP 1; [(n-Bu 3Sn)4Fe(CN)6H2O] consists of octahedral [Fe(CN)6]4- building blocks which are connected by the TBPY-5 configured n-Bu3Sn(CN.)2 fragments creating 3D-network structure. Fenton and photo-Fenton oxidative discoloration of Methylene Blue (MB) has been investigated by hydrogen peroxide catalyzed with the SCP 1. The reaction exhibited pseudo first-order kinetics with respect to each of MB and H2O2. The irradiation of the reaction with UV-light enhanced the rate of MB mineralization, Kobs = 0.76 h -1. Mineralization of MB was investigated by FT-IR spectra. Disodium salt of terephthalic acid photoluminescence probing technology was carried out to identify the reactive oxygen species. The different parameters that affect MB degradation rate were evaluated. Moreover, the efficiency of recycled the SCP 1 and the mechanism of degradation of MB dye were investigated. © 2013 Elsevier B.V. All rights reserved.
