摘要
本文研究了磷酸中铅、铁的测定方法,并讨论了磷酸产生的背景干扰和背景吸收校正,获得满意的结果。其回收率为92.7%-106.5%,测量精度小于11.43%。
In this paper a method for determination of Pb and Fe in phosphoric acid was studied,and the BKG absorption correction and BKG interferences produced from phosphoric acid were discussed. The results are satisfactory.The recoveries are between 92. 7% and 106. 5% and RSD is less than 11. 43%.
