| 摘 要： | 本文报道用原子吸收分光光度法测定稀土磷酸盐催化剂中助剂铜,不必经过萃取、分离等其它过程,而用酸溶处理后,在空气一乙炔燃焰中,直接测定微量铜的方法。结果表明:无论采用标准曲线法还是标准加入法测得的铜含量基本相同。在本工作确定的实验条件下,磷酸稀土背景对分析结果的影响可以忽略不计,而方法的准确度、精密度均在0.1～1.8%、0.0～1.2%之间。

| Abstract: | The essay describes the conditions: sample treatment and quantitative methodof the content of copper in rare-earth phosphate catalyst by atomic absorptionspectrometry. The results have shown that the sample was dissolved in HNO_3 anddirectly determined in C_2H_2 Air flam ebut there was no need for extraction and sep-aration. At the same time whether adopting standard curve method or adopting stand-ard adding metbcd the content of the copper determined was unanimous. In thecondition of this exeriment the effect of of the background of the rare earth phosphateions were overlook. The ratative error and ratative deviation of this method was1. 8--0. 1% and 0. 0 0. 12%. |
