摘要
通过巯基棉富集分离后 ,用火焰原子吸收光谱法测定了食盐中的痕量镉 ,研究了巯基棉富集 Cd( )的条件 ,实验回收率 92 %— 98% ,RSD<6 .0 %。本实验方法简便 。
Trace cadmium in salt was enriching and separating with sulfhydryl cotton under optimized condition,and determined by FAAS.The recovery is 92%—98%.RSD is less than 6.0%.The method is simple and convenient.
