【摘要】:正汞是环境中毒性最强的重金属元素之一,它具有持久性和长距离迁移性等特点。有色金属冶炼工业,特别是锌冶炼工业,是一个重要的大气汞污染源。因此,准确测定再生锌原料中汞的含量,对冶炼工业中汞污染的控制具有重要的意义。通常采用比色法、滴定法、电感耦合等离子体原子发射光谱法(ICP-AES)、电感耦合等离子体质谱法(ICP-MS)、冷原子吸收光谱法和原子荧光光谱法等进行汞的测
[Abstract]:Positive mercury is one of the most toxic heavy metal elements in the environment. Non-ferrous metal smelting industry, especially zinc smelting industry, is an important source of atmospheric mercury pollution. Therefore, the accurate determination of mercury content in regenerated zinc raw materials is of great significance to the control of mercury pollution in smelting industry. Determination of mercury is usually carried out by colorimetric method, titration method, inductively coupled plasma atomic emission spectrometry (ICP-AESN) method, inductively coupled plasma mass spectrometry (ICP-MS) method, cold atomic absorption spectrometry (ICAAS) and atomic fluorescence spectrometry (AFS).
