摘要：

A method for atomic-absorption determination of 17 types of microimpurities in high-purity mercury at a detection limit of 10(-6) - 10(-7) wt.% is described. The method is based on preliminary concentration df impurities in solution, reduction of mercury ions to the elemental state with formic acid, and separation of mercury from the concentrate. The method is checked for correctness by a recovery test ("added - found"). The relative standard deviation is 0.03 - 0.07.
