DIN CEN/TS 16182:2012-05

This Technical Specification (CEN/TS 16182) describes a method for the determination of nonylphenols (NP), nonylphenolmonoethoxylates (NP1EO) and nonylphenol-diethoxylates (NP2EO) in the matrices sludge, treated biowaste and soil using GC-MS. After pretreatment, the test sample is extracted by shaking with a mixture of acetone and petroleum ether (1:1). The extract is treated with N-methyl-N-(trimethylsilyl)-trifluoracetamide (MSTFA) reagent for the derivatization (silylation) of the analytes, and subsequently analysed by gas chromatography and mass selective detection (GC-MS). Nonylphenols and nonylphenol-mono- and diethoxylates are identified from the GC fingerprint, the relative retention times and the relative intensities of two diagnostic ions. The quantification is based on an internal standard procedure. For sludge a limit of detection of 0,1 mg/kg and for soil and treated biowaste 0,02 mg/kg (expressed as dry matter) may be achieved. Due to the data collected in collaborative studies and consultations with the interested parties within CEN member organizations, it has been decided that this document CEN/TS 16182 is suitable for the application. CEN/TS 16182 has been prepared by Technical Committee CEN/TC 400 "Project Committee - Horizontal Standards in the fields of sludge, biowaste and soil", the secretariat of which is held by DIN, Germany. The responsible German committee is NA 119-01-02-02 UA "Chemische und physikalische Verfahren" ("Chemical and physical processes") of NA 119-01-02 AA "Abfall- und Bodenuntersuchung" ("Examination of waste and soil") at the Water Practice Standards Committee (NAW).
