摘要
以某垃圾焚烧厂焚烧炉产生的烟道气为研究对象,采用酒石酸提取,对烟道气中Sb形态进行了分析,用HG-AFS分别测出样品中Sb(Ⅲ)和总Sb的量,差减法得到Sb(Ⅴ)的量。结果表明,Sb(Ⅲ)和总Sb检出限分别为0.13μg/L和0.11μg/L,相对标准偏差(RSD,n=11)分别为5.8%和6.3%,加标回收率在84.8%~113%。
A method for the determination of speciation of Sb (Ⅲ ) and Sb ( V ) in fly ashes from MSW (municipal solid waste) incinerator by hydride generation atomic fluorescence spectrometry ( HG - AFS) is reported. The extraction condition of complexible Sb ( Ⅲ ) and Sb ( V ) are discussed. The results show that the detection limits of the method for Sb ( Ⅲ ) and Sb (total) are 0. 13 μg/L and 0. 11 μg/L respectively. The recoveries of standard addition for Sb (Ⅲ ) and Sb (total) are 84.8 % -113 % with precision of 5.8% RSD and 6.3 % RSD (n = 11) respectively.
