摘要
本文提出一个快速同时分光光度测定锑、锡和锗的方法。锑、锡和锗经磷酸三丁酯萃取后,用苯基萤光酮显色,各配合物重叠光谱的相互干扰用CPA-矩阵法处理,方法简捷,灵敏度及准确度均较好,用于合成样品及河流沉积物中锑、锡和锗的测定,获得满意的结果。
A simple method for simultaneous spectrophotometric determination of Sb, Sn and Ge has been developed. Sb, Sn and Ge were extracted by tributyl phosphate (TBP) and then reacted with phenylfluorone. The interference of overlapping spectra of complexes for spectrophotometric determination of these three elements can be overcome by using the computation of CPA (the inverse expression of Beer-lambert's law)matrix method.The method was applied to the determination of Sb,Sn and Ge in the river sediment with satisfactory results.
