Ammonium cerium(IV) nitrate, 99.99%. L961. Ammonium cerium(IV) nitrate, AR, >=98% Nitrate et fixation de l’azote. C’est le premier maillon de la dégradation de l’azote atmosphérique : l’azote de l’air étant stable, les nitrobactéries « fixatrices » font sauter ce verrou en dégradant l’azote atmosphérique en ammoniums (ammoniac NH3 et ions nitrates NO3-.). As long as nitrate concentrations remain under control, the product is not exhausted. Each 500 mL of de nitrate™ treats about 100–200 L (25–50 US gallons), depending on initial nitrate concentration and the current biological load. Enough should be used to remove nitrate at a rate at least as fast as the rate of formation.

== More of My 2021-04-10 · Nitrates Le Figaro Santé Le nitrate (NO3-) est un ion produit au cours du cycle de l’azote, particulièrement soluble dans l’eau et responsable d’une pollution des eaux. La principale source d’azote réside dans l’atmosphère sous forme de diazote (N2) qui représente un peu moins de 80% de la composition de l’air. Crystallized from aqueous nitrate solutions with pH < 0, the core cluster structures exhibit variable decoration by nitrate, glycine, and water ligands depending on solution conditions, where increased nitrate and glycine decoration of the cluster core was observed for crystals synthesized at high Ce and nitrate concentrations.
