Ammonium ions are generated by ammonia reacting with proton donors. When ammonia is dissolved in water, a significant amount of it reacts with the hydronium ions in water to give ammonium ions. Ammonia contamination is often historic in nature and often found on old coal carbonisation plant sites
QROS offer an on-site technique that allows us to quantify the level of exchangeable ammonium in soil within approximately 20 minutes. The method is suitable for soil and water samples.
Also available are on-site techniques for the determination of soluble sulphate and soluble chloride.
