摘要
本文研究了ＰＡＮ－Ｓ与铟的显色条件。配合物的最大吸收峰位于５４２ｎｍ波长处，表观摩尔吸光系数ε为２．２７×１０￣４Ｌ·ｍｏｌ￣（－１）·ｃｍ￣（－１），２５ｍｌ溶液中铟量ρ（Ｉｎ￣（３＋）／（μｇ·ｍｌ￣（－１））在０－３．２范围内服从比尔定律。用巯基棉分离矿石中共存离子富集铟，选择性好，方法用于矿石中微量铟的测定，结果个人满意。
This paper studies the condition of colour reaction of indium with PAN-S. The maxi-mum absorbance of the complex is at 542 nm and its apparent molar absorptivity iS 2.27×10￣4L·mol￣(-1)· cm￣(-1).Beer’s law is obeyed in the range of 0-3.2μg/ml for indium,The common metal ions can be separated by sulfhydryl cotton fiber with high selectivity,The method has been used to determine the trace indium in ores and results are satisfactory.
