I'm using Ammonium Cerium Nitrate to neutralize phosphate-buffered saline solutions containing 0.1% Sodium Azide. I add 0.55 grams of Ammonium Cerium Nitrate into 100 mL of this 1XPBS + 0.1% NaN3 solution and am able to neutralize the NaN3.
Will the resulting solution have any negative, harmful, effects if flushed down the drain? My main concern is polluting ground water or corroding our sewerage system.
