摘　　要：本研究以硝酸镍作为基体改进剂,采用石墨炉原子吸收光谱法测定染料中砷的含量,标准曲线在0~30μg/L范围相关线性良好,相关系数r≥0.9995,样品加标回收率在85%~115%,符合检测要求,是测定染料中痕量砷的良好检测方法.In this paper,the content of arsenic in dye was determincd by graphite furmace atomic absorption spectrometry with nickel nitrate as matrix modifier.The results showed that when the linear range was 0-30 μg/L,the corrclation cofficient r≥0.9995,and the recovery rate was 85%-115%,it was a good method for the determination of trace arsenic in dye.
