Total mercury in urine determined by direct mercury analyzer

    Abstract
  • ObjectiveTo establish a direct determination method for urine mercury
    MethodsDMA80 Direct Mercury Analyzer was applied in determination of the total mercury in urine.
    ResultsThe method showed a good linear relationship within the concentration range of 1.0-200.0 ng.The detection limit of this method was 0.4 μg/L, with the precision between 0.38% and 1.68%.The recovery rate was between 92.6% and 96.9%.
    ConclusionThe method can be used as a conventional method in determination of the total mercury in urine.
