Synthesis, characterization of hydroxyl-Fe-pillared -bentonite and its use in heterogeneous photo-fenton degradation of ro se bengal
Abstract The degradation efficiency of rose bengal in aqueous medium using the heterogeneous photo-Fenton process has been assessed. It was found that, the heterogeneous photo-Fenton process was relatively more suitable as compared to its homogeneous counterpart. In heterogeneous system, the catalyst can be reused and the possible pollution caused by the ferrous ions in solution of homogeneous process can also be avoided. Through cation exchange reaction, Hydroxyl-iron-pillared-bentonite was prepared and used as a solid catalyst for photo-Fenton process.
