采用微波消解法处理大米样品、石墨炉原子吸收光谱法测定大米中镉的含量。此方法的线性范围为0~100.0 ng/mL（R=0.9993），加标回收率为97.78%~100.29%，RSD为0.35%~3.37%（n=6）。该方法取样量少、准确度和精密度高，可作为检测大米中镉含量的方法，为食品安全提供可靠的测定技术保障。
採用微波消解法處理大米樣品、石墨爐原子吸收光譜法測定大米中鎘的含量。此方法的線性範圍為0~100.0 ng/mL（R=0.9993），加標迴收率為97.78%~100.29%，RSD為0.35%~3.37%（n=6）。該方法取樣量少、準確度和精密度高，可作為檢測大米中鎘含量的方法，為食品安全提供可靠的測定技術保障。

Rice samples were dealt with microwave digestion ,then cadmium's content were determined by graphite furnace-atomic absorption spectrometry.The linear range of cadmium's absorption spectrometry was 0 . 0-100 . 0 ng/mL ( R=0 . 999 3 ) . The adding standard recovery was 97 . 78 %-100 . 29 %. The RSD was 0.35 %-3.37 %(n=6).This method in which sampling quantity was little, degree of accurancy and degree of precision were high , can be used for detection of cadmium in rice and provided reliable technical support for food safety.
