Trace lead in baked food is determined by air-acetylene flame atomic absorption spectrometry (FAAS) with APDC-DDTC-MIBK as the extraction and preconcentration system after cineration process.
A flow injection on-line adsorptive preconcentration system with a knotted reactor (KR) for flame atomic absorption spectrometric (FAAS) determination of trace lead was developed.
