尿中汞的测定,是职业病汞中毒的诊断治疗中的一项重要工作,长期以来,国内均采用双硫腙-氯仿萃取比色测定。在实践中,存在着双硫腙-氯仿萃取物的变黄,以及其他金属离子干扰等问题。另外,对分析工作者来说,长期经常接触氯仿,难免对健康引起不同程度的影响。近年来,园内外先后应用原子吸收法代替双硫腙法测定含汞化合物中的汞,该法操作简便,且所用试剂不多。为此,我们应用国产F732测汞仪,探讨对尿、
Determination of mercury in urine is an important work in the diagnosis and treatment of occupational disease mercury poisoning. For a long time, the domestic use of dithizone - chloroform extraction colorimetric determination. In practice, there is the problem of yellowing of the dithizone-chloroform extract and interference with other metal ions. In addition, for analysts, long-term regular exposure to chloroform, will inevitably have varying degrees of health effects. In recent years, the park has applied atomic absorption spectrometry instead of dithizone method for determination of mercury in mercury-containing compounds, the method is simple and convenient, and the reagents used are few. To this end, we use domestic F732 mercury analyzer to explore the urine,
