Fenton's reaction offers several advantages, including high efficiency in generating hydroxyl radicals, the ability to degrade a wide variety of organic compounds, and the use of relatively inexpensive and non-toxic reagents. However, there are also limitations to consider. The reaction is highly pH-dependent, typically requiring an acidic environment (pH 2.5-4.0) for optimal performance. The precipitation of iron hydroxides can also cause operational issues and necessitate additional treatment steps to remove the iron sludge.
