摘　　要：本文介绍了运用红外光谱测定闪锌矿中硫化铁分子摩尔百分含量的新方法。这一方法用样量少、简便、迅速,只要测出闪锌矿的红外光谱特征吸收频率,根据公式FeS(mol%)=-0.126+2.162(x-309),或作图,就能容易地获得闪锌矿中硫化铁分子摩尔百分含量。Introduced in this paper is a new method——infrared spectroscopy which is used to determine the content of FeS(mol%) in sphalerite. This method has many advantages such as limited sample requirement, convenient operation and rapid performance. The measurement of the infrared spectral characteristic absorption frequency of sphalerite in the light of the formula FeS (mol%)=-0.126+2.162(x-309) by diagrammatization is vital to the acquirement of the FeS (mol%) content of sphalerite.
