Reflectance based optical fibre sensor for ammonium ion using solid-state Riegler's reagent
A new optical sensor for fast screening of ammonium (NH4+) ion was developed based on immobilisation of p-nitrobenzene-diazonium chloride (Riegler's reagent) onto XAD-7 microbeads. In aqueous solution, the diazonium salt is unstable and will spontaneously decompose at room temperature but we ha...
