摘要: |
采用火焰原子吸收光谱法的标准加入曲线法测定食品添加剂磷酸中钠含量,并进行精密度、准确度和检出限测定试验。结果表明,钠在0.25~2.00μg.ml-1浓度范围内标准曲线性良好,回归方程为r=0.9999,RSD=2.02%,平均回收率为96.0%~108%。本方法简便、快速、灵敏度,能够准确地测定磷酸中钠的含量,结果令人满意。 |

Abstract: |
It's determined sodium content in phosphoric acid by additive of stomdard with method flame atomic absorption spectrum,it's tested with precision,accuracy and detection limit.It's indicated that standard curve's linearity is well at range of concentration from 0.25 to 2.00μg·ml-1,r=0.9999,RSD=2.02%,it's from 96.0% to 108% of average callback,This method is quick,simple,ingenious and satisfied with determing sodium content in phosphoric acid. |
Key words: atomic absorption spectrum sodium phosphoric acid |
