摘要
试样用稀王水分解,于6%王水介质中,使用空气-乙炔气火焰于波长223.1nm处,原子吸收光谱法测定铋。本方法可用于测定锡矿石中0.020%~2.00%的铋。
In this study, the sample was broken down by thin aqua regia, and in the 6 per cent water medium, the air-acetylene flame was used in the wavelength of 223.1nm, and the atomic absorption spectrometry was used to determine the bismuth. This method can measure the bismuth of 0.020%- 2.00% in the tin ore.
