ICP-OES法快速测定煤系硫铁矿中的铜、铅、锌

Rapid determination of copper,lead and zinc in the pyrite of coal by ICP-OES

采用盐酸—硝酸溶解,盐酸提取,利用电感耦合等离子体发射光谱(ICP-OES)法,通过对射频功率、分析谱线和观测方式的优选,无需基体匹配,即可实现煤系硫铁矿中铜、铅、锌的快速测定;该方法具有准确度高、重复性好、可多元素快速测定等优点。

With the hydrochloric acid-nitric acid dissolution and the hydrochloric acid extraction, by the Inductively Coupled Plasma Atomic Emission Spectroscopy( ICP-OES),through the optimization of the radio frequency power,the analytical line and the observation methods, the rapid determination of copper,lead,and zinc in the pyrite of coal is achieved with no matrix matching. The ICP-OES has the advantages of high accuracy,good repeatability,and rapid determination for multiple elements.
