With the increasing focus on removing emerging, unregulated drinking water contaminants, the use of advanced oxidation processes (AOPs) has become more prevalent. A commonly used AOP is the ultraviolet light/hydrogen peroxide (UV/H2O2) less harmful forms. In this analysis, two alternative solid forms of H AOP. This process utilizes the formation of hydroxyl radicals to oxidize contaminants to 2O2, sodium perborate (SPB) and sodium percarbonate (SPC) were used as sources of H 2O2 in the UV/H2O2 AOP. The potential advantage of SPB and SPC is that they are solids in nature, and as a result, the shipping costs and shipping energy requirements can be reduced significantly compared to that of liquid H 2O2.
