Determination of lead in medicinal plants by high-resolution continuum source graphite furnace atomic absorption spectrometry using direct solid sampling

A procedure is proposed for Pb determination in medicinal plants by high-resolution continuum source graphite furnace atomic absorption spectrometry (HR-CS GF AAS) using direct solid sampling. Among Pd(NO3)2, Pd/Mg(NO3)2, NH4H2PO4 and the W-coated platform tested as chemical modifiers, Pd(NO3)2 pres...
