摘　　要：以硝酸镁为助剂干法灰化、浓硝酸浸取残渣分解纯棉样品.ICP-AES 全谱直读光谱仪为检测手段.优化选择 ICP-AES 工作参数,考查了样品灰化温度,助剂用量及基体元素的干扰行为.准确测定了棉纺织品中的As、Cd、Co、Cr、Cu、Ni、Pb 和 Sb 8种痕量重金属元素总量.杂质元素分析结果 RSD%皆小于4.样品加标回收率在90%～98.2%之间.元素检出限在0.4～10.2μg·L^(-1)之间.The cotton textile samples were digested by adding magnesium nitrate-auxiliaryashing and nitric acid . After optimizing the operating parameters of ICP-AES,ashing temperature of the samples,auxiliary concentration and interference of the matrix. Auxiliary concertra- tion and interference of the matrix were investigated. Total ammount of the heavy metals induding As, Cd, Co, Cr, Cu, Ni, Pb, Sb in cotton cloth were determinated by ICP-AES. The elements recoveries of Standrad addition method were 90. 0 %~ 98.2 %. The overall relative Standard deviation was within 4.00 %. The detection limits were 0.4～10.2μg·L^-1.
