一种痕量砷化氢气体的吸收介质及其制备方法、痕量砷化氢气体的检测装置及检测方法
摘要：
本发明涉及一种痕量砷化氢气体的吸收介质及其制备方法、痕量砷化氢气体的检测装置及检测方法，属于环保技术领域。本发明痕量砷化氢气体的吸收介质为表面负载有银离子的海藻酸钠胶体颗粒；所述海藻酸钠与银离子摩尔比为30:1～40:1；所述胶体颗粒中水分含量为35％～40％。采用本发明痕量砷化氢气体的吸收介质对砷化氢进行检测，方法简单，灵敏度高，对砷化氢的吸收率高达97.32％。
摘要（英）：

The invention relates to an absorbing medium for a trace arsenic hydride gas, a preparation method thereof, a detection device for the trace arsenic hydride gas and a detection method and belongs to the technical field of environmental protection. A sodium alginate colloidal particle with silver ions loaded on the surface serves as the absorbing medium for the trace arsenic hydride gas provided by the invention; the mole ratio of sodium alginate to silver ions is at (30:1)-(40:1); and the moisture content in the colloidal particle is 35%-40%. The absorbing medium for the trace arsenic hydride gas provided by the invention is used for detecting arsenic hydride, the method is simple, the sensitivity is high and the absorptivity of arsenic hydride is as high as 97.32%.
