Abstract:
The dispersive liquid-liquid microextraction (DLLME) method of detecting N-nitrosoamines (NAs) is a DLLME performed with a xylene extraction solvent and a methanol disperser solvent. The microextraction is preferably performed by a programmable array logic (PAL) auto-sampler. Determination and measurement of concentration of the NAs in the water sample being found by a gas chromatograph coupled with a mass spectrometer (GC-MS).
