报道了用自制的在线氢化物连续发生装置 ,应用端视 ICP- AES法测定水中痕量硒和汞。不需要专用氢化物发生装置 ,分析成本低。在完成非氢化法测定或氢化法测定时不需拆卸或安装。方法简便、快速。测定水中硒和汞的测定 ,其检出限分别为 2× 1 0 -4 和 1× 1 0 -4 mg· L-1。
Reported the use of home-made continuous hydride line device, the application of end-visual ICP-AES determination of trace selenium and mercury in water. No special hydride generation device is required and the analysis cost is low. In the completion of non-hydrogenation method or hydrogenation determination without disassembly or installation. The method is simple and fast. The detection limits of selenium and mercury in water were 2 × 10 -4 and 1 × 10 4 mg · L -1, respectively.
