摘　　要：建立了固体、液体中汞的直接测定方法。采用直接测汞法,样品无需任何消解,无论固体样品还是液体样品均可用汞原子蒸气在253.65 nm处的特征吸收进行测定,方法灵敏度高、简便、快速、准确。通过对某燃煤锅炉装置所有排放污染物中汞的分析,确定了燃煤锅炉煤中汞的迁移和分配规律,为汞污染治理提供了技术支持。Mercury in solid or liquid samples can be quantitatively analyzed at 253.65 nm using direct mercury analyzer without any digestion procedure. The method is simple, sensitive and accurate. Coal and its combustion products were analyzed to study mercury distribution and transportation in coal fired boiler, which could provide technical support for control and treatment of mercury pollution in the coal combustion process.
