Overview
EN 15484:2007 (CEN) specifies a potentiometric method for the determination of inorganic chloride in ethanol used as a blending component for petrol. The procedure measures chloride in the aqueous solution obtained after evaporating an ethanol test portion and dissolving the dry residue. The method covers chloride concentrations from 4 mg/l to 30 mg/l and is widely used for fuel quality control and regulatory compliance.
Warning: the method involves hazardous reagents and laboratory operations; users must follow appropriate safety and regulatory requirements.
Key topics and technical requirements
- Scope and range: quantitative determination of inorganic chloride in ethanol, 4–30 mg/l.
- Sample preparation: evaporate a weighed ethanol test portion, dry residue (oven), dissolve in deionised water and make up to volume before titration.
- Analytical principle: potentiometric titration of chloride with silver nitrate (AgNO3) using a silver or halide ion-selective measuring electrode and a calomel or double-junction reference electrode. Endpoint detection uses recorded potential increments to calculate Veq.
- Reagents and solutions: analytical-grade reagents including AgNO3 standard solutions, potassium chloride (KCl) reference solutions, acetone, nitric acid and high-purity water (EN ISO 3696 grade 3).
- Apparatus: potentiometer, measuring/reference electrodes, magnetic stirrer, burettes, evaporating dishes, oven, dessicator and analytical balance.
- Calibration and blanking: standardisation using KCl reference solutions and parallel reagent blank determination are mandatory.
- Calculation and expression: concentration calculated from titration volumes, standardisation factor and chloride atomic mass; results rounded to 0.1 mg/l.
- Performance: repeatability r = 0.9 mg/l; reproducibility R = 1.6 mg/l.
- Interferences: Annex B lists known interferences (other halogens, oxidizing agents, certain ions); users must assess sample-specific interference potential.
Applications and users
- Fuel quality and compliance testing for ethanol-blended petrol
- Ethanol producers and refineries performing incoming/outgoing QC
- Independent analytical laboratories and notified bodies verifying chloride content
- Blending plants and fuel distributors monitoring corrosion-related contaminants
- Regulatory agencies and standards organizations enforcing fuel specifications
