摘要
本文建立湿法快速消解-原子荧光光谱法测定蔬菜中的总砷含量。结果表明,砷浓度在0~10μg·L^(-1)时,方法的线性关系良好,相关系数大于0.999,检出限为0.02μg·L^(-1),回收率为93.3%~102.4%,相对标准偏差为2.9%~4.5%。该方法操作简便,重现性良好,准确可靠。
A fast wet digestion-atomic fluorescence spectrometry method for the determination of total arsenic content in vegetables was developed.The results showed that when arsenic concentration was 0~10μg·L^(-1),the linear relationship was good,the correlation coefficient was greater than 0.999,the detection limit was 0.02μg·L^(-1),the recoveries were 93.3%~102.4%,and the relative standard deviations were 2.9%~4.5%.The method is simple,reproducible,accurate and reliable.
