Estimate the theoretical carbonaceous and nitrogenous oxygen demand of a waste containing 50 mg/L lysine, C6H14N2O2. Assume the nitrogen is liberated as ammonia in the first oxidation step converting organic carbon to CO2. Can I calculate this as just theoretical oxygen demand, or is there a way to separate it into carbonaceous and nitrogenous oxygen demand?
A grad student made the news for all the WRONG reasons a few years ago when he synthesized a "nickel hydrazine perchlorate" compound (but didn't give any more detailed information) on a scale 1000 times larger than what his lab advisor told him to..
