| Inhoud: |
Experimental and thermodynamic evidence is presented to show that nitrate-N can be reduced beyond nitrite-N in a cadmium reductor. The studies are made in a batch system and include the effect of sample to reductor ratio. Data presented show that aqueous ammonium-N can be oxidized to nitrite-N at a rate of about 0.0.-0.04 percent per day in the presence of air and cadmium-copper or cadmium-mercury complex. The rate of this oxidation, unaffected by absence of light, is reduced to the order of 0.001 percent per day or less in a nitrogen atmosphere and cadmium-mercury complex. Hence a requirement for air is suggested for the oxidation reaction. |
