| 摘 要： | 通过试验研究,建立了硝酸-氢氟酸-高氯酸消解、石墨炉原子吸收分光光度法测定生活垃圾堆肥产品中的镉。该方法的检出限为0.01mg/kg(按称取0.5g试样消解定容至50mL计算),用于不同地域堆肥样品中镉的测定,其相对标准偏差(RSD)在5.78%～11.9%之间,加标回收率介于88.0%～106.0%之间,可作为一种较理想的检验堆肥产品质量的方法。

| Abstract: | On the basis of experiment,a determination method of cadmium in composting products of household waste was developed by graphite furnace atomic absorption spectrophotometry(GF-AAS) and sample digestion with HNO3-HF-HClO4.The method was applied to the determination of cadmium in composting products of various regions,with relative standard deviation between 5.78%～11.9% and recovery rate of 88.0%～106.0%.The determination limit was 0.01mg.kg as calculated by weighing 0.5g sample,digesting and diluting with water to 50mL volume.The method is reliable to examine the quality of composting products. |
