WebAs a result of shifting the carbonate-bicarbonate equilibrium, the pH of the ocean is also changing. Texas A&M University oceanographer Kathryn Shamberger says ocean pH has dropped from 8.2 to 8.1. Continuing to release carbon dioxide at the current rate will mean the oceans will continue to increase in acidity. WebMany advanced oxidation processes (AOPs) use Fenton-like reactions to degrade organic pollutants by activating peroxymonosulfate (HSO5–, PMS) or peroxydisulfate (S2O82–, PDS) with Fe(H2O)62+ (FeaqII).
