Overview
EN 16195:2012 is a CEN European Standard that specifies an analytical method for the determination of chlorides in fertilizers free from organic material. Adopted in November 2012, the method is applicable to all inorganic fertilizers without organic content and describes sample preparation, reagents, apparatus, titration procedure and result expression. The procedure is based on a classical argentimetric titration (Volhard’s method) and includes quality checks and precision data from an inter‑laboratory study.
Key Topics
- Scope and applicability: Only for fertilizers that are free from organic material; sampling itself is not included but EN 1482-1 and EN 1482-2 are referenced for sampling and sample preparation.
- Analytical principle: Chlorides are dissolved in water and precipitated with excess silver nitrate (AgNO3, 0.1 mol/L). The excess Ag+ is back‑titrated with ammonium thiocyanate (NH4SCN, 0.1 mol/L) in the presence of ferric ammonium sulfate (indicator) - classic Volhard’s method.
- Reagents & apparatus: Requires chloride‑free water, nitric acid (10 mol/L), indicator solution (Fe/NH4 sulfate), nitrobenzene or diethyl ether to prevent AgCl/thiocyanate interaction, burettes, volumetric flasks, Erlenmeyer flasks, and a rotary shaker (35–40 min‑1).
- Procedure essentials:
- Prepare a test extract from a 5 g laboratory sample in 500 ml water (shake 0.5 h).
- Take an aliquot containing ≤0.150 g Cl (e.g., 25–100 ml), acidify, add indicator, add excess AgNO3, add nitrobenzene/ether, then back‑titrate excess Ag+ with NH4SCN until a persistent red‑brown end point.
- Perform blank and control tests; calculate chloride as mass fraction (%) using the volumes of titrants and sample mass (formula provided in the standard).
- Precision: Inter‑laboratory data (2009) give repeatability and reproducibility limits. Example: for a sample with mean Cl 2.781% - r = 0.066% and R = 0.284%; for mean 0.478% - r = 0.076% and R = 0.312%.
Applications
- Quality control and specification testing in fertilizer manufacturing (inorganic fertilizers).
- Routine analysis in analytical laboratories performing fertilizer compliance testing.
- Use by regulatory authorities and conformity assessment bodies to verify chloride content where organic matrix interference is absent.
- Applicable when chloride quantification is needed for product labelling, formulation checks, or to assess corrosivity and soil salinity implications.
