EurekAlert!: NH3 synthesis via visible-light-assisted thermocatalytic NO reduction by CO in the presence of H2O over Cu/CeO2
NH3 synthesis via visible-light-assisted thermocatalytic NO reduction by CO in the presence of H2O over Cu/CeO2
NH3 and NH4 together are often referred to as total ammonia nitrogen (TAN). Under normal conditions, NH3 (ammonia) and NH4 (ammonium) will both be present in aquarium water. The two exist at an equilibrium point that is governed largely by pH and temperature. However, salinity and the ionic strength of the water also influence this equilibrium ...
Using traditional methods free ammonia (NH3) is very hard to measure so normally people measure non-toxic ammonium (NH4) in the aquarium and pond and use this as a guide to safe levels of NH3. In true terms NH4 is a nontoxic substance in the aquarium, however due to the equilibrium which occurs between NH3 / NH4 at a given pH and temperature it is better to measure NH4 as an indicator of NH3 ...
NH3 is reported in the unit of ppm but this is interchangeable with mg/L as it is a gas dissolved in water. Want to reduce your ammonia because you have a high level or problem?
NH3-N test kit ouput ammonia measurement If you are using a Photometer or Reagent test that measures NH3-N or TAN then care needs to be taken to understand exactly what is being measured. There are a number of test methods that measure "Ammonia" & NH3 however, it is not always as simple as reading the value. Is an Ammonia or NH3 test kit reporting the same NH3 value as seneye? In short, No ...
