Sludge treated biowaste and soil — Determination of nonylphenols (NP) and nonylphenol-mono- and diethoxylates using gas chromatography with mass selective detection (GC-MS)
ADOPTED_FROM:CEN/TS 16182:2012
This Technical Specification specifies a method for the determination of nonylphenols (NP), nonylphenol-monoethoxylates (NP1EO) and nonylphenol-diethoxylates (NP2EO) in sludge using GC-MS.
For sludge a limit of detection of 0,1 mg/kg and for soil and treated bio-waste 0,02 mg/kg (expressed as dry matter) may be achieved.
Lower limits of detection may be achieved by concentrating the extract by solvent evaporation.
NOTE 4-tert-octylphenol can also be analysed with this method.
