近年来常采用加入适量亚硒酸钠的含碘盐来预防克山病。为经常监测硒盐的适宜浓度和体内含硒水平,我们用国产930型萤光光度计建立了毛发和硒盐中微量硒的测定方法。 毛发 称取已处理好的毛发0.5000—1.000g(约含硒0.05μg)于磨口三角瓶中加混酸A*7ml,5％钼酸钠液3ml,置电砂浴 In recent years, often by adding appropriate amount of sodium iodide salt of sodium selenite to prevent Keshan disease. To regularly monitor the appropriate concentration of selenium and selenium levels in the body, we use a domestic 930 fluorescence spectrophotometer to establish the determination of trace amounts of selenium in hair and selenium. Hair Weigh hair has been processed 0.5000-1.000g (about selenium 0.05μg) in the grinding mouth flask mixed acid A * 7ml, 5% sodium molybdate solution 3ml, set electric sand bath
