摘　　要：分别采用HCl-HNO3-HF-HClO4全消解和HCl-HNO3-HF快速消解对土壤进行消解,用石墨炉原子吸收分光光度法测定其中铅的含量。结果表明,快速消解的准确度、精密度均符合要求,与全消解相比,其所需的消解时间大大缩短、所用酸量大为减少。The methods for determination of lead in soils bycomplete digestion(HCl-HNO3-HClO4)and incomplete digestion(HCl-HNO3-HF)-graphite furnace atomic absorption spectrophotometry were developed in this study.The results showed that the incomplete digestion technique with good accuracy and precision which meet the requirements.The digestion time was shortened and smaller amount of acid compared with the complete digestion greatly.
