Nitrite reduction reaction

WebbNitrate and nitrite reduction reactions The reactions were carried out in a 250-mL batch reactor. In a typical experiment, the catalyst was introduced in the reactor and degassed under N 2 upflowing. 90 mL of ultrapure water with predissolved hydrogen was then added and the temperature was lowered to 10°C. WebbNitrate reaction occurs only under anaerobic conditions. The mediu m is dispensed in tubes to give a low surface area to depth ratio which limits the diffusion of oxygen into the medium. ... Nitrate, present in the broth, is reduced to nitrite which may then be reduced to nitric oxide, nitrous oxide, or nitrogen (see Figure 1).
