ABSTRACT
This study established a method for determination of heavy metals such as Cu, Zn, Ni, Cr, and Mn in soil by flame atomic absorption spectrometry using graphite digestion device. A pretreatment process was confirmed after the pretreatment condition such as digestion system and amount of sample for digestion were optimized. The detection limits are 0.62, 0.48, 0.45, 0.53 and 0.50 mg/kg for Cu, Cr, Zn, Ni and Mn, respectively. Recoveries are between 96.5% and 105%. RSD are between 0.8% and 2.0%.
