• Solid phase extraction
• Atomic absorption spectrometry
• Trace metal enrichment
• activated carbon with nanometer pore size distribution (AC-NPD)
• 2-(4-methoxybenzylideneamino) thiophenol

A new low cost and efficient activated carbon (AC) with nanometer pore size distribution has been prepared from acorn. AC physically impregnated with 2-(4-methoxybenzyl-ideneamino)thiophenol (2-4-MBDAT) efficiency was used for the simultaneous preconcentration of trace amount of Cu2+ and Zn2+ ion from some food samples. The proposed sorbent at optimum conditions of all variables has adsorption capacity of more than 60 mg g(-1) with pre-concentration factor of 170 for both ions. The recoveries of analytes were generally higher than 94% with relative standard deviation lower than 4.10%. The method successfully applied for enrichment and determination of these ions from high volume sample solution.
