Article Highlights

• A direct solid sobent sampling procedure for flame atomic absorption spectrometry was developed.
• Solid sorbents were used to extract metals and transport them to the flame of FAAS.
• Proposed method was highly sensitive for the determination of trace metals.
• Proposed method was reproducible even for a manual sampling.
• Other sorbents can be efficiently used for lead, cadmium and other metals.
