摘要
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。
A microwave digestion-flame atomic absorption spectrometry （FAAS） has been developed for determination of rudimental metal impurity-zinc and nickel in 2,4,6-trichloro-phenylhy drazine. By microwave, digestion was more quicker and more environment-friendly. Results showed the RSD for Zn was 1.18% and 0.37% for Ni, the average recovery was 95% -105%.
