摘要
将食用油灰化处理后 ,用APDC -DDTC -MIBK体系萃取富集试液中的镉 ,利用空气 -乙炔火焰原子吸收法测定其含量。建立了优化的测定条件 ,并对可能存在的元素作了干扰实验。结果表明 ,测定镉的相对标准偏差为 1 8%～ 3 1% ,回收率为 97 1%～ 10 1 5 % ,结果十分满意。
After the cineration of the edible oil,the cadmium in it was extracted by the APDC-DDTC-MIBK system,and the content of cadmium was then tested with air-acetylene flame atomic absorption spectrometry(FAAS).The optimum testing conditions were established and a test for the probably existing interference elements was performed.The relative standard deviation of the test was 1.8% to 3.1%,the respective recovery rate was 97.1% to 101.5%.The result of the test is satisfactory.
