采用微波消解-火焰原子吸收法,测定了2,4,6-三氯苯肼中的残留锌和镍。用微波消解试样,大大缩短了试样前处理时间且环保。结果表明,该法测定锌和镍的相对标准偏差分别为1.18%和0.37%;加标回收率在95%～105%之间,结果可靠。 Residual zinc and nickel in 2,4,6-trichlorophenylhydrazine were determined by microwave digestion-flame atomic absorption spectrometry. Microwave digestion of the sample, greatly reducing the sample pre-treatment time and environmental protection. The results showed that the relative standard deviations of zinc and nickel determined by this method were 1.18% and 0.37%, respectively. The recoveries of spiked samples ranged from 95% to 105% with reliable results.
