摘要：

Methylene Blue was treated with the catalytic ozonation method, with first ever use of alum as a novel ozonation catalyst.Both simple ozonation and catalytic ozonation were efficient treatment processes; however, maximum removal efficiency for Methylene Blue of 86% was achieved by alum based catalytic ozonation process.On optimizing pH to 6.6, maximum removal efficiencies for Methylene Blue improve to 85% and 99% for simple ozonation and catalytic ozonation processes, respectively.The improved results for catalytic ozonation are owed to predominant hydroxyl radical mechanism.
