易切钢中铅含量一般为0.10～0.35%。对铅含量的测定,采用化学分析法,操作复杂;采用极谱法,原子吸收光谱法,一般中小型工厂目前尚无条件。我们设想,用看谱镜作看谱定性分析,把铅含量控制在0.10～0.35%范围以内,即可满足生产需要。我们参考了铜合金中测铅的分光标志,采用火花光源,由于铅4057.82(?)、5005.43(?)和5201.4(?)线分别受到锰4057.95(?)线、铁5006.1(?)、5202.34(?)线干扰,故采用了铅线5608.8(?),取得了满意效果,结果与原子吸收光谱法一致。
Easy to cut the lead content of steel is generally 0.10 ~ 0.35%. The determination of lead content, the use of chemical analysis, the operation is complex; using polarography, atomic absorption spectrometry, the general small and medium-sized factories currently no conditions. We envisaged the use of spectroscopy as a spectroscopic qualitative analysis, the lead content control in the range of 0.10 ~ 0.35%, to meet the production needs. We refer to the spectral sign of lead in copper alloy, using spark light source. Because the lead 4057.82 (?), 5005.43 (?) And 5201.4 (?) Are respectively affected by the 4057.95 (?) Line, 5006.1 (?), 5202.34 ?) Line interference, so the use of the lead line 5608.8 (?), And achieved satisfactory results, the results consistent with atomic absorption spectrometry.
