Abstract

The immersion liquid method is powerful for the measurement of the refractive index of solid particles in a liquid matrix. However, this method applies best for cases when the liquid matrix is transparent. A problem is usually how to assess the refractive index of a pigment when it is in a colored host liquid. In this article we introduce a method, and show that by combining so-called multifunction spectrophotometer, immersion liquid method and detection of light transmission and reflection we can assess the refractive index of a pigment in a colored liquid, and also the extinction or absorption coefficient of the host liquid.

摘要

浸没液法在测量液体基质中固体颗粒的折射率方面非常强大。然而，这种方法最适用于液体基质透明的情况。通常的问题是如何评估彩色基质中颜料的折射率。在本文中，我们介绍了一种方法，并表明通过结合所谓的多功能分光光度计、浸没液法以及光透射和反射的检测，我们可以评估彩色液体中颜料的折射率，以及主液体的消光或吸收系数。
