还原性或氧化性气氛下Ni对气态二价汞的催化还原探讨

Catalytic Reduction of Gaseous Mercury with Reducing or Oxidizing Atmosphere

原子吸收光谱技术基于Hg原子蒸气(Hg^0)对253.7 nm的紫外光的选择性强吸收作用实现Hg含量的测定,所以,保证样品中所有形态的Hg转化为Hg^0,是获得Hg含量准确测量的前提条件之一。运用HSC热化学模拟软件中的平衡相计算模块对过渡周期中的Ni对气态Hg^(2+)的还原效果进行了分析。

Atomic absorption spectrometry （Hg0） is based on the selective absorption of 253.7 nm ultraviolet light by Hg atom vapor （Hg0） to determine the Hg content.Therefore, to ensure that all forms of rig in the sample are converted to Hg0, the Hg content can be accurately measured The precondition of it.Using the equilibrium phase calculation module in the HSC thermochemical simulation software, the reduction effect of Ni on the gaseous Hg2＋ during the transitional period was analyzed.
