砷在地面水分析中是一重要的元素,国家规定饮用水卫生标准对砷的最大允许深度为0.04毫克/升,从而要求有一个灵敏度较高的分析方法。用氢化物发生—原子吸收分光光变法测定痕量砷,有其更多的优点。本文应用这一技术并对氢化物发生器的设计及分析条件等进行改进,结果较为满意。 Arsenic is an important element in surface water analysis. The maximum allowable depth of arsenic in drinking water standards stipulated by the state is 0.04 mg / L, which requires a more sensitive analytical method. Determination of trace arsenic by hydride generation-atomic absorption spectrophotometry has its advantages. This application of this technology and hydride generator design and analysis of conditions to improve, the results are more satisfactory.
