| 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%. |
