Hello,
Upon writing my paper, I noticed that most journal papers stated the concentration of all nitrogen compounds in -N , example instead of NH4+ its NH4+-N. I knew that the -N form uses the molecular weight of only the nitrogen atoms from NH4+.
Is it appropriate to write the concentration of NH4+ in paper writing? Or should I convert the NH4+ in the form of NH4+-N? Please advise. Thank you very much.
It really depends on the the audience or journal for which you are writing. In my experience, looking at water quality or concentrations in soil, the convention is to to convert everything to a –N basis. But this is not always done. If the journal articles you are reading use convert everything to an –N basis, then that's that will probably be the best approach. This is as common for NH4–N as it is for NO3–N.
Hello Salvatore S. Mangiafico . Thank you for your advice. NO2, NO3, TKN and NH4+ are the major parameters to measure for water quality . I found that a lot of journal papers mentioning the nitrite concentration as NO2-N instead of NO2-.
Is there a difference between between NO2-N and NO2- or is it the same value when typing, exemple: -[NO2-N] = 13,5 mg/l, -[NO2-] =13,5 mg/l.
Is there a relations to convert [NO2-] to [NO2-N]?
To make it simple to sum the components they are typically expressed as N
