摘要
介绍以硫酸亚铁铵为还原剂的硅钼蓝光度法对钢铁中的硅进行测定,并研究了相应的显色反应条件。试验结果表明:此法用于钢铁中硅的测定具有良好的选择性,灵敏度高,稳定性及重现性好等优点。测定范围在0-50μg/50mL内遵守比耳定律。
This experiment used ferrous sulfate ammonium to making the reducing agent and silicon molybdenum blue luminosity law to silicon in the steel and iron. The corresponding color reaction condition have been studied. The tests show that the proposed method has been applied to determine silicon in steel samples with very good selectivity, sensitivity, stability and recurrence. Beer＇s law is obeyed in the concentration rang of 0 -50ug/50mL for silicon.
