ISO 17380:2013 specifies a method for the photometric determination of the total cyanide and easily-liberatable cyanide content in soil using automated distillation/continuous-flow analysis. ISO 17380:2013 applies to all types of soil with cyanide contents above 1 mg/kg on the basis of dry matter, expressed as cyanide ion.

Overview

EN ISO 17380:2013 (ISO 17380:2013) specifies a laboratory method for the photometric determination of total cyanide and easily-liberatable cyanide in soil using automated distillation combined with continuous‑flow analysis (CFA). Published by CEN/ISO, the standard applies to all soil types with cyanide concentrations above 1 mg/kg (dry matter) and is intended for routine, high‑throughput analysis where reliability and reproducibility are required. The document includes safety notes (cyanide solutions are highly toxic) and guidance on sample pretreatment, reagents, apparatus and calculations.

Key topics and technical requirements

Principle: Soil is extracted with 2.5 mol/L NaOH (16 h), diluted (100×) and analyzed by an automated distillation/CFA manifold with photometric detection.

Determinations: Provides procedures for both total cyanide (includes complex cyanide after UV decomposition) and easily‑liberatable cyanide (weakly bound species measurable under the method conditions).

UV decomposition: Complex cyanides are broken down in a continuously flowing stream using UV‑B irradiation and a borosilicate decomposition coil; buffer initial pH ~3.8 is used.

Analytical range & interferences: Applicable for soil cyanide contents >1 mg/kg; sulfide concentrations >40 mg/kg (dry matter) interfere and may require sample dilution. Organic cyanides (e.g., acetonitrile) are not determined.

Quality control: Calibration graphs, system checks, cleaning/maintenance of CFA apparatus, precision and recovery data, and reporting requirements are specified.

Safety: Emphasizes toxicology and safe disposal of cyanide-containing solutions.

Applications and practical value

Environmental monitoring of contaminated sites, brownfield assessment and soil quality surveys.

Mining and mineral processing: monitoring cyanide in tailings and soils near gold or base‑metal operations.

Remediation verification: tracking reductions in total and easily‑liberatable cyanide during treatment.

Waste management and regulatory compliance: supporting permits and environmental risk assessments.

High‑throughput analytical labs benefit from automation (CFA + automated distillation) for large sample series with consistent photometric results.
