本文建立了一种活性炭同时富集水中铅、镉、铜、锌、铁、锰、镍、锶、铊的技术,结合火焰原子吸收法,可测定水中超痕量水平的上述金属。对9份平行样品测定的变异系数为2.5～10.5%,样品加标回收率为78.5～114%。用本法测定了自来水、河水、深井水、雨水等样品,除雨水中未检出铊外,均检出了上述元素。 In this paper, a technology for the simultaneous enrichment of lead, cadmium, copper, zinc, iron, manganese, nickel, strontium and thallium in activated carbon has been established. Combining flame atomic absorption spectrometry, the above metals in ultra-trace levels in water can be determined. The coefficient of variation of 9 parallel samples was 2.5 ~ 10.5%, and the spiked recoveries were 78.5 ~ 114%. Using this method to determine tap water, river water, deep well water, rain and other samples, except thallium not detected in rainwater, all the above elements were detected.
