摘要
本法采用碳酸钡、氟化锂、石墨粉作缓冲剂,用锑做铅锌的标,用铪作铌的内标,用钯作铍、铬、镧、锶、铜的内标。采用小孔电极,交流电弧做为激发光源,同时测定铅、锡、锌、铍、铬、镧、铌、铜、锶等九个元素。分析数据基本稳定,能达到土壤样品的检出限要求。
The method adopts barium carbonate,lithium fluoride and graphite powder as buffering agent. Uses Sb as the internal standard of Zn, Pb and Sn. Uses Hf as the internal standard of Nb. Uses Pd as the internal standard of Be, Cr, La, Sr and Cu. To adopt small hole electrode and alternating current arc as excitation light source to analyze the contents of Pb , Sn, Zn, Nb, Be, Cr, La, Cu and Sr. The experiment proves that the data of analysis is basically fixed and it ean meet the requirement of detection limit of soil samples.
