摘要
本文研究无钠灯情况下,根据火焰发射原理,用原子吸收分光光度计测定Na的含量。工作曲线相关系数r2为0.9933。该法灵敏度高,选择性好,操作简便,工作曲线稳定,用本法测定Na的含量,结果令人满意。
Without any sodium lamp, atomic absorption spectrophotometry was used to determine the content of sodium according to the principle of flame emission. The coefficient of correlation (r2) for working curves was 0. 9933. This method has high sensitivity and good selectivity, is easy to manipulate and produces stable working curves.
