摘　　要：本文建立电感耦合等离子体发射光谱法测定木家具色漆中铅镉铬汞4种可溶性重金属含量的检测方法。试验结果表明:待测元素在0.1~10.0 mg/L浓度范围内线性关系良好,相关系数大于0.99989,方法检出限为0.0314~0.7543 mg/kg,定量限为0.1045~2.492 mg/kg,相对标准偏差(RSD)为0.09%~3.04%,相对误差为4.6%~7.6%;加标回收率为94.33%~112.0%。该方法具有检测限、定量限低,精密度、准确度高,快速等优点,适用于检测木家具色漆中可溶性重金属含量。Establish a detection method for the determination of four soluble heavy metals in wood furniture paint by ICP-OES.The results showed that the linear relationship between the four soluble heavy metals was good within the concentration range of 0.1~10.0mg/L,with a correlation coefficient greater than 0.99989.The limits of detection(LODs)and the limits of quantification(LOQs)ranged from 0.0314 to 0.7543mg/kg and 0.1045 to 2.492mg/kg,respectively.The relative standard deviations ranged from 0.09%to 3.04%.The relative errors ranged from 4.6%to 7.6%.The recoveries ranged from 94.33%to 112.0%.This method have the advantages of low detection limit and quantitative limit,high precision and accuracy,and rapid in detection,and is suitable for detecting the soluble heavy metal contents in wood furniture paints.
