摘要
采用微波辅助提取-液相色谱-氢化物发生-原子荧光光谱法(LC-HG-AFS)联用技术分析了太湖沉积物中砷的形态[亚砷酸(As(III))、二甲基砷酸钠(DMA)、一甲基砷酸二钠(MMA)和砷酸As(V)]。测得沉积物中以无机砷为主,且以As(V)居多。选定以1mol/L的磷酸和0.1mol/L抗坏血酸为提取液,在微波辅助萃取(功率为60W,时间12min)下,萃取率达79.84%~91.57%,回收率在94.78%~107.6%之间。4种砷的形态在0~160μg/L之间时线性良好,检测限为0.6~2.3μg/L,相对标准偏差RSD为1.62%~2.20%。方法具有简便、快速、灵敏的特点。
