| 摘 要： | 用自制的冷原子汞蒸气发生装置和样品吸收管,研究了以SnCl_2为还原剂,冷原子吸收分光光度法连续测定汞的适宜条件.检出限为0.45ng/ml,汞量在0～80ng/ml范围内,符合比尔定律;连续测定浓度为20ng/m的汞溶液,相对标准偏差为1.8%;测定实际水样中的痕量汞,其回收率为97.0%～100.8%.

| Abstract: | A sensitive method for continuous determination of trace mercury in wastewater by cold vapour atomic-absorption spectrometry, using SnCl_2 as reductant was studied. Apparatus for producing cold mercury vapour and closed-end quartz absorbing lube were used. The detection limit (S/N-2) and relative deviation were 0.45ppb and 1.75% respectively. |
