电感耦合等离子体发射光谱法同时测定电厂排水中多种重金属元素

Simultaneous determination of heavy metal elements in drained water of thermal power plant by ICPAES.

用硝酸加热消解火电厂排放水,用电感耦合等离子体发射光谱法测定其中的重金属元素Cd、Cr、Pb、Ni、Cu、Mn。该方法快速简便,可以实现多种元素同时测定。精密度和回收率符合要求。

The drained water of thermal power plant was digested with nitric acid under heating condition and the heavy metal elements （Cd, Cr, Pb, Ni ,Cu and Mn） in it were determined by ICP-AES simultaneously. The method is rapid and convenient and the precision and recovery can meet the requirement of determination.
