中文摘要：比较两种样品消解方法即高压密封消解法和常规湿法消解法,用火焰原子吸收光谱法测定马氏珠母贝中微量镉的含量。结果表明:测定采用高压消解罐法消解的马氏珠母贝中镉含量为60.96 mg/kg,湿法消解法的为61.65 mg/kg,测定结果没有明显差异,测定RSD均小于3%,回收率结果分别为97.44-101.29%和96.77-102.19%。两种消解方法相对设备要求简单,花费少,均能满足分析测定要求,符合绝大部分实验室条件,相比之下高压密封消解操作更简单,方便,消耗酸量更少。

外文摘要：Two kinds of sample digestion methods,high pressure airproof digestion and conventional wet digestion,were tested for determination of cadmium content in Pinctada martensii by flame atomic absorption spectrometry.The results showed that the cadmium contents in Pinctada martensii by high pressure digestion digestion and wet digestion were 60.96 mg/kg and 61.65 mg/kg,respectively.The RSD were less than 3% and the recovery by the two methods were 97.44-101.29% and 96.77-102.19%,respectively.Both of the two methods required relatively simple equipments and low cost.Digestion with high pressure airproof was more facile,convenient and needed less consumption of acid than wet digestion.
