Determination of Heavy Metals in 2,6-Dichloro-4-Nitroaniline by ICP-MS
2,6-Dichloro-4-nitroaniline was pretreated by microwave digestion,and 13 heavy metals in the samples were quantitatively analyzed by inductively coupled plasma mass spectrometry(ICP-MS).The limit of detection was in the range of 0.001～0.187 μg/L,the relative standard deviation(RSD)was less than 2％,and the recovery rate was 96.08％～112.00％.The results showed that the method was feasible and could be a reference for the analysis of heavy metal contents in 2,6-dichloro-4-nitroaniline.
