This investigation demonstrates that both ammonia and acetic acid, which are refractory intermediates in metabolic waste destruction by hydrothermal oxidation, are more effectively oxidized with hydrogen peroxide than oxygen at lower temperatures. Results highlight the differences between the two oxidants and offer an explanation of the disparities presented in the literature regarding the similarities and dissimilarities of peroxide and oxygen in hydrothermal systems. Furthermore, evidence is presented that shows acetic acid and ammonia may be destroyed better in combination than separately.
