碘量法和火焰原子吸收法在测定硫铁矿低铜含量准确性的讨论

Discussion on the Accuracy of Iodometry and Flame Atomic Absorption Spectrometry in the Determination of Low Copper Content in Pyrite

碘量法是测铜的经典方法,此方法测定范围较宽;对高含量(铜精矿)的测定尤为常用。但在测定硫铁矿低铜含量样品时,碘量法没有火焰原子吸收法测定准确。

Iodometry is a classical method for determination of copper.This method is widely used for determination of high content(copper concentrate).However,when determining the low copper content sample of pyrite,the iodometric method is not as accurate as the flame atomic absorption method.
