ISO 15320:2011 specifies a test method for the determination of pentachlorophenol (PCP) in an aqueous extract of pulp, paper and board. Although it was developed for paper and board intended to come into contact with foodstuffs, it is applicable to all kinds of pulp, paper and board. The working range for acetylation is 0,05 mg/kg to 0,5 mg/kg.

Overview

ISO 15320:2011 specifies a laboratory test method for the determination of pentachlorophenol (PCP) in an aqueous extract of pulp, paper and board. Originally developed for paper and board intended to contact foodstuffs, the method is applicable to all types of pulp, paper and board. The method uses aqueous extraction (cold or hot), concentration by solid-phase extraction (SPE), chemical derivatization (acetylation) and quantification by gas chromatography with electron-capture detection (GC‑ECD) or gas chromatography–mass spectrometry (GC‑MS). The working range for acetylation is 0.05 mg/kg to 0.5 mg/kg.

Key topics and technical requirements

Scope and sampling

Applicable to pulp, paper and board; sample selection per ISO 186 or ISO 7213.
Minimum sample required: 10 g (oven-dried); determine dry matter per ISO 638.

Extraction

Cold-water extraction: 10 g sample, 200 ml water, 24 h at (23 ± 2) °C.
Hot-water extraction: 10 g sample, 200 ml boiling water, 2 h in 80 ± 2 °C water bath.

Concentration and cleanup

Solid-phase extraction using phenyl silica SPE columns (e.g., 500 mg/3 ml).
Elution with n‑hexane into a potassium carbonate receiver.

Derivatization

Acetylation with acetic anhydride to form acetylated PCP for GC analysis.

Quantification

Internal standards: 2,3,6‑trichlorophenol for ECD; 13C6‑labelled PCP for MS.
Calibration by plotting area ratio versus mass ratio; report results in mg/kg of material.

Instrumentation

GC conditions and detector settings are specified; GC‑MS can use SIM/SIR for sensitivity.

Safety note

Method involves toxic or corrosive reagents (PCP, methanol, acetic anhydride, sulfuric acid). Users must follow appropriate safety and environmental practices.

Applications and users

ISO 15320:2011 is intended for:

Testing laboratories performing routine quality control and compliance testing of paper and board (including food-contact materials).

Manufacturers and converters in the pulp and paper industry monitoring PCP residues.

Regulatory bodies and certification bodies verifying conformity with chemical safety limits.

Research labs conducting trace-level analytical development for chlorinated phenols.

Practical benefits: reliable, standardized approach for low-level PCP determination; adaptable for GC‑ECD or GC‑MS workflows; suitable for regulatory reporting and product safety verification.
