本文采用蒸馏方法对硃砂及含硃砂中成药进行处理,使其中游离汞随水蒸汽蒸出,经氧化吸收再还原,用无焰冷原子吸收光谱法测定汞。经蒸馏条件试验、回收率测定、精密度试验中药及硃砂共存元素的干扰试验等,证实该分析方法准确可行。 In this paper, the cinnabar and Chinese cinnabar-containing proprietary Chinese medicines were treated by distillation method, in which the free mercury vaporized with water vapor, and was absorbed and reduced by oxidation. The mercury was determined by flameless cold atomic absorption spectrometry. Distillation condition test, recovery rate measurement, precision test Chinese medicine and interference test of cinnabar coexisting elements, etc., confirmed that the analysis method is accurate and feasible.
