用活性炭对汞吸附富集，可测定汞浓度低于冷原子吸收法检出限的饮水水样．这种方法使汞被解析后，不经滤除活性炭而直接还原测定．平行样测定的相对偏差和加标回收率结果表明，该方法简便、实用．有较好的精确度和准确度
Adsorption and enrichment of mercury with activated carbon can be determined mercury concentrations lower than the detection limit of cold water absorption water samples. This method allows the mercury to be analyzed without direct filtration after removing the activated carbon. The relative deviation of the parallel sample determination and the recovery of the spiked samples show that the method is simple and practical. Better accuracy and accuracy
