将自制钽丝圈原子化器与原子吸收光谱仪联用，以氩气作保护气，测定了Ｃｄ、Ｃｕ、Ｍｎ、和Ｐｂ，研究这一原子化器的性能。在选定的仪器工作条件下，测定Ｃｄ、Ｃｕ、Ｍｎ和Ｐｂ的特征质量浓度分别为０．７μｇ／Ｌ、１７μｇ／Ｌ、２８μｇ／Ｌ和３１μｇ／Ｌ。对实际样品中的Ｃｕ和Ｍｎ进行了测定，其结果令人满意。该法具有简便、廉价的特点。 The homemade tantalum wire ring atomizer and atomic absorption spectrometer with argon gas as the protective gas, determination of Cd, Cu, Mn, and Pb, to study the performance of this atomizer. Under selected instrument operating conditions, the characteristic mass concentrations of Cd, Cu, Mn and Pb were determined as 0.7 μg / L, 17 μg / L, 28 μg / L and 31 μg / L, respectively. The actual samples of Cu and Mn were determined, the results are satisfactory. The law is simple, cheap features.
