Primary tabs
ISO/TS 13907:2012 specifies a method for the determination of nonylphenols (NP), nonylphenol-monoethoxylates (NP1EO) and nonylphenol-diethoxylates (NP2EO) in sludge, treated biowaste and soil using GC-MS.
For sludge, a limit of detection of 0,1 mg/kg and for soil and treated biowaste of 0,02 mg/kg (expressed as dry matter) may be achieved.
