在环境样品中常含有μg/L 或 mg/L 水平的砷。通过密闭容器,在高压氧下燃烧分解样品,所生成的砷化氢可用原子吸收进行测定。试剂砷(Ⅲ)标准溶液:取光谱纯砷用蒸馏水稀
Arsenic is often found in environmental samples at μg / L or mg / L levels. Through a closed container, under high pressure oxygen combustion decomposition sample, the generated arsine can be determined by atomic absorption. Reagents arsenic (Ⅲ) standard solution: Take pure arsenic diluted with distilled water
