Bu çalışmada insan saçında talyum için doğrudan katı örneklemeli atomik absorpsiyon spektrometresi ile tayini için yöntem geliştirilmiştir. İnsan saçı örnekleri aseton, destile deiyonize su ve tekrar aseton ile yıkanmış ve 75 oC’de kurutulmuştur. Saç örnekleri doğrudan katı örneklemeli oto-örnekleyiciye yüklenmiştir. Katı örnekleme tekniği ile talyum tayini için piroliz/atomlaşma sıcaklığı, madde miktarı ve bunlara modifier (Pd/Mg) ve/veya yardımcı reaktiflerin etkisi incelenmiştir. Aletsel ve deneysel parametreler optimize edildikten sonra iki farklı sertifikalı referans maddesi ile geri kazanım çalışmaları yapılmıştır. Talyum için ortalama geri kazanım % 94’tir. Talyum için tayin sınırı (3σ, N=10) sırasıyla 0.0067 μg/g’dır.
