摘要
建立了电感耦合等离子体发射光谱仪(ICP-AES)法同时测定染料中12种重金属元素As、Cd、Cr、Co、Cu、Fe、Hg、Mn、Ni、Sb、Pb、Zn的含量。各元素的线性相关系数均≥0.999,方法检出限为0.26~1.65 mg/kg;同时进行加标回收试验,不同浓度的加标回收率在89.7%~106%,精密度为1.09%~4.51%,可以满足测定的要求。
Twelve heavy metals in dyestuffs, including As, Cd, Cr, Co, Cu, Fe, Hg, Mn, Ni, Sb, Pb, Zn are determined by ICP-AES. The linear correlation coefficient of each element is greater than or equal to 0.999, the detection limit is 0.26-1.65 mg/kg. In the recovery test. recovery rate in different concentra- tion is 89.7%~106%, the precision is 1.09%-4.51% which can meet the requirement of tests.
