Advanced Oxidation of Drinking Water Using Ultraviolet Light and Alternative Solid Forms of Hydrogen Peroxide

摘要

With the increasing focus on removing emerging, unregulated drinking water contaminants, the use of advanced oxidation processes (AOPs) has become more prevalent. A frequently used AOP is the ultraviolet light/hydrogen peroxide (UV/H_2O_2) AOP. This process utilizes the formation of hydroxyl radicals to oxidize contaminants to less harmful forms. In the research presented here, two solid forms of H_2O_2, sodium perborate (SPB) and sodium percarbonate (SPC) were used as non-traditional sources of H_2O_2 in the UV/H_2O_2 AOP. The potential advantage of SPB and SPC is that they are both solids in nature, and as a result, the shipping costs and shipping energy requirements can be reduced significantly compared to that of liquid H_2O_2.
