作者研制了高压湿法消化器,并用于人体痕量元素分析样品的前处理,与新极谱阳极溶出伏安法、示波极谱阳极溶出伏安法和石墨炉原子吸收分光光度法联用,作了血铅,发铅测定的平行实验和回收实验,回收率达97.1~99.1%。测定血铅183例、发铅36例、指甲铅25例,证明采用高压湿法消化器进行人体痕量元素分析样品前处理,可有效地提高分析方法的灵敏度和准确度。
The author developed a high-pressure wet digester and was used in the pretreatment of human trace-elemental analysis samples, in combination with new polarographic anodic stripping voltammetry, oscillopolarographic anodic stripping voltammetry and graphite furnace atomic absorption spectrometry , Made blood lead, lead determination of parallel experiments and recovery experiments, the recovery rate of 97.1 ~ 99.1%. Determination of 183 cases of blood lead, hair lead 36 cases, nail lead 25 cases, the use of high pressure wet digester human trace elemental analysis of samples pretreatment, can effectively improve the sensitivity and accuracy of the analytical method.
