铜合金中铁和锰的火焰原子吸收分光光度测定法

Atomic Absorption Spectrometric Determination of Ironand Manganese in Copper Alloys

本文建立了以火焰原子吸收分光光度计同时测定铜合金中铁、锰两元素的方法，该法以硝盐混酸溶解试样，在标准系列中加入基体铜以扣除背景影响，其中杂质元素，如锌、铝、铅、镍、锑、铋、锡等，对测定铁和锰元素均无影响。方法简便快速，准确度符合要求，结果令人满意。

In this paper the atomic absorption spectrometric method in simultaneous determination of iron and manganese in copper alloys is presented. The nitric-hydrochloric acid was used to dissolvethe sample.In order to eliminate the background effect,the base copper was added into the calibration solution. The impurity elements in copper alloys ,such as zinc,aluminium,lead,nickel,antimony, bismuth and tin, etc.,will not interfere with the determination.The recommended method not only proved to be simple and rapid but showed satisfying accuracy as well
