Abstract:Several wet digestion and dry ashing procedures for the simultaneous determination of ten elements (Fe,Cu,Mn, Zn, Co, Mo, Cr, Sr, Ni and Pb) by ICP-AES in traditional Chinese medicines were investigated. The results suggested that dry ashing with HNO_3 and (NH_4)_2HPO_4 was satisfactory, Of the methods tested, wet digestion with HNO_3-H_2O_3 (4:1 ) was also efficient. The methods established have been successfully applied to the determination of 10 trace elements in native medicinal materials in Sichuan with satisfactory results.
Keywords:ICP-AES  traditional Chinese medicines  ashing  wet digestion
